Heater fan stays on

Hi Folks,

Came home from work tonight and SWMBO informed me that when she got home and switched off the car the heater fan stayed on. Sure enough I checked the car and the battery was flat.

I've got the battery on a trickle charger at the moment and have disconnected the fan to prevent it from draining the battery but it means no heat or demister.

Now, the car was put through a car wash at the weekend. The area the fan sits in (under the dash on the passenger side) is soaked and so is the passanger footwell so I guess there's a drain hole blocked or a leak below the windscreen.

I'm assuming the water ingress has casued a short somewhere but if anyone could suggest a likely palce to look I'd appreciate some pointers.

Really need to get this working ASAP as SWMBO is heavily pregnant, due in the next few weeks, and our mechanic is swamped at the moment so we'll be waiting a few days before they can even look at it.

Sounds like the speed controller /Resistor. It lives behind the fan unit in the passenger footwell.

Have just had to replace mine. Have a search for it on here.
