Phase 1 Spyder cooling fan nightmare!
Hi Guys this is my first of no doubt many posts on the forum so thanks in advance for any advice.
Picked up a 1996 basket case Spyder Phase1 for a song recently but already my wallet is rapidly emptying - I know I know!
First of many problems is the bizarre behaviour of the rad cooling fan!
After 10 seconds of the engine starting first the low speed fan and then a few seconds later the high speed fans cut in and stay on permanently until the engine is switched off. If you immediately turn the key to the MAR position the fans stay off!
I have changed the sensor on the thermostat to avail and tested the relay operation using Multiscan - there are also no fault codes stored. I'm guessing the resistors are both fine too as both speeds work.
I have been told the ECU might have a dry solder joint inside so can't read the signal from the sensor so goes to default mode.
Have tried to find similar cases to mine but no luck - apologies if I missed any.
Anyone got any ideas?
