Hi,
Has anyone had experience or knowledge about the heater fan and its operation on a 164?
Our 164 is a '93 TS Lusso, and has climate control with the multi-button switch panel in the centre console.
The fan has stopped working. The display on the dashboard display (the LCD bars) seems to respond correctly to the pressing of the two buttons, but the fan does not start.
I have read on a previous thread that there is a fuse located in the engine compartment near the brake cylinder. Where is the fan itself, how is it accessed and removed, and is there a relay or something else I can fault find? Has anyone had this fault and what did they trace the defect to?

Many thanks
Roger164

Thanks for the tip. I found some useful info, I hope anyway. So the fan, 40A fuse and relay, and a controller or regulator or something are behind the bulkhead - you need to remove the thin plastic cover that runs the width of the engine compartment, just in front of the wipers. I've got that far at least, by torchlight, this evening! Will give it a look this weekend and let you know if I find anything.:)

Interesting reading other threads on the site, which seems mainly American - based(?) one which caught my eye was about a guy wanting to know about the feasibility of running a 164 as daily transport. In 2001, in the US at least, it seems spares were not a problem. Then again, the 164 had only been discontinued for 3 years or so. How things of changed, and I wonder how many 164s are still on the road or regularly used.

The fan speed controler sits inside the heater box on the driver's side - near the pollen filter slot.

The fan itself is over on the other side near the wiper motor. On a V6 i's JUST possible to change it from the engine bay so it probably is on the TS too. First thing to do would be to locate the wires feeding the fan and put 12 volts across them to see if the fan motor turns. If it does, the problem is elsewhere.

As previously stated the item in question is just under the cover at the engine bulkhead nearside. It is just a link rated at 40A, in my opinion way over rated. I replaced it with an in line fuse holder with a 10A fuse. Its been in there 12 mths or more and still is ok.

Have traced the fault, having identified most of the component parts. It is the little Siemens relay which sits under a larger cover next to the 40A fuse. The coil is open circuit. So the next step is to order a new one....hopefully not another huge wait from A-R!:rolleyes: I wonder if I can get one from anywhere else (any ideas, anyone?)

Let me have a few more details of the relay ie number colour etc and exact location as Ive boxes of bits of 164s.

Thanks Bogart.

It is manufacturered by Siemens and carries the numbers as follows:

V23134-J52-X182

7606542

12V/50A

It is coloured black.

There are four terminals - two for the coil, and two for the N/O contacts, which are of course quite big, as it's 50A rated.

It is of the same size / dimensions as other relays used on the car - the sort which is about 1" square. However it's type / rating is differnent!

Thanks again:)

Hi

Have what I believe is what you are after.
Part number is quoted as 7752313 and no mention of Siemens but no surprise there.
Cannot get my AR parts list up on the pc to check compatability, again no surprise there.
The giveaway is that it is marked 12V 50A. The main contacts are large and at right angles to each other.

If this sounds the part let me have your address and i will pop it in the post.

Regards

Hi,

Many thanks Bogart, very kind of you. I will check the contact arrangement as I did not note what it is on mine, and let you know.

regards

Bogart, Hi
I think I'm sorted thanks - unexpectedly, the local Alfa people have found one from somewhere (I'd been preparing for the usual 3 month wait!), which they say they will get in in next day or so. Amazing.
Anyway, we will see....
Many, many thanks for turfing through your boxes of bits though, much appreciated; there's some nice 164 owners out there for sure! If I'm let down by the Alfa people I might come back cap in hand though!:)
cheers,
Roger

Any idea how to get the interior lights, and boot button to work?

I' am glad I didn't suggest my method for getting my fan to work. Drive over a pot hole, or kick the center console!

The guy on about 164 as daily transport earlier, I use mine every day for work, and lots of long journeys. Reliable when it works, stopped because rotor arm disintegrated, and it ran on fluff for 250miles until the rev sensor fried. I had not realised on a long run, noticed reduced power and it didn't run right but it stopped before I worked out the problem. I thought it was the computer or distributer, and that it would have stopped earlier with a broken rotor arm! Also another time the tensioner pulley for auxillary belt siezed, snapped the belt and stopped the battery from charging. Also sensor on the air intake came undun, and air filter fell off. Both fixed at the side of the road in 2 mins though! So 3 stops in 2 years for a 16 year old car in daily use not too bad I think.

I have found a few electrical things fix themselves before I get time to look at it!

(I do service it when required, and get odd suspension bits, exhaust, brakes and tires, but that would be the same in any car)

Any way interior lights, not the relay (unless there is another one somewhere), fuse, or bulbs, any ideas?

Thanks,
Paul

Paul,

Thanks for recounting your experiences with your 164, I don't think we have anything so spectacular - may be all to come? :lol:

Can't help with the interior lights problem. I take it that they are utterly dead, by that I mean it's not just the 'coming on when you open a door' bit which isn't working?

The boot release problem - have you checked the relay or solenoid?

If your car is the same as our '93 model, then the relay is located inside the boot on the RHS - pull back the boot trim near to the fuel filler pipe and you'll see it, together with another (similar) relay which operates the fuel filler cap solenoid.

The solenoid for the boot release is wired from the N/O contacts side of the relay (the heavier wires) and is in the boot lid next to the lock.

I can't remember for sure, but I think that the two relays share a common 12V wire for the two coils, which loops from one to the other (red on ours). I think the switch on the dashboard, when pressed, closes a contact in the coil return wire to energise the relay.

When you hold down the button on the dash you should get a continuous 12V signal to the coil (i.e. it's not a pulse signal) so if you put a meter on it and get someone to press the button you should be able to see the coil volts sit at 12V if all is OK from the button!

This should also allow you to prove whether it is the relay or the button on the dash which is defective. If you get 12V in the boot, then thank your luck stars it is not that switch panel or vehicle wiring somewhere - you should be able to trace it down to the relay or solenoid, with any luck.

Hope that makes some sense and helps!

cheers
Roger

Thanks Roger.

It may be hard to believe but I have had an old Alfa for a while and still don't have a multi-meter. I will get one.

My car had been off the road for 2 years before I got it, and it started first time! The rev sensor is a common thing to go wrong, and it has to be calibrated by Alfa, or similar. I hope they sorted that for the "newer" models!

Don't use a unipart rotor arm!

The interior lights are dead. The bulbs work, I have tested them, but they never come on. When I get a meter I will tinker with them again.

I just wanted you to know that a 164 makes a good car for daily use. I do 15k+ miles a year, and find it surprisingly economical. The large boot will take all my tools and a 21" honda lawn mower (I am a gardener), and unlike an estate no one can see in it! I know the purists would think it was all wrong, but the running costs are part of my tax equation, and I don't see many others still driving these great machines.

Get in touch with EBspares, if you have parts problems that Alfa can't solve. I am lucky my local Alfa garage can be bothered to check the parts list over the whole UK and sometimes Europe to get what I need sometimes. A lot have been broken so second hand parts often available.

Happy driving!

Paul

Thanks Paul

Ours has been pretty good - three failures in last two years, during which the car has been used regularly, around 7-8K/ year. Before that the car was off the road for two years too. It was in storage I surpose - I have owned the car for the last 10 years. Before it went into 'store' it was totally reliable. Like you we appreciate the big boot; most new cars are several inches longer and wider with similar boots (with the exception of the Skoda Octavia).

And now - engine still terrific, bodywork hardly any corrosion....

What great cars the 164 is eh?

Alfashop are good for bits too. They got me a reconditioned front brake caliper for around 30 quid for example. When I lived in London it was great as ther is loads of ex-Alfa franchise specialists around; Alfa 2 in Stanford off Honeypot Lane looked after mine - impeccably.
Now, our local Fiat Alfa people are slightly bemused whenever it comes in, but as they say it gives them another challenge! The last time they had to ring Italy to get them to fax through some wiring schematics!

cheers
Roger
