Heater Controls And Clock Stopped Working

[paulh]

My problem started when the rear washer pipe split and flooded the passenger footwell, tis in turn took out the parking sensor control unit. This has been removed as they've never worked anyway and all seemed well.

However the heater controls have stopped working, as has the illumination, and also the clock.

I've checked all the fuses and they are all fine, I've removed the heater control unit god knows how many times and cleaned the contacts etc but nothing seems to be solving it.

Is there another fuse hidden somewhere? Surley the revesing sensor unit doesn't need to be plugged in, or does it?

Help!!

Hi,

 

I had this exact problem, my heater blower stopped working plus other strange electrical happenings. The flood from your washer pipe has got the loom wet and has rotted the relay control wires. I had a vehicle electrician show me the problem and I could not believe the way the loom is put together at his point. The relay control wires are basically stripped at the ends, twisted together and soldered. When the loom gets wet this "twist" part rots and disconnects stopping the relays operating, hence no heater and other stange happenings.

 

The solution is simple, in the nearside passenger footwell (in the flooded region) you have to get to the loom and carefully cut the outer wrapping of the loom. Examine the area and you will see one part where three or four different coloured wires have been twisted together at the ends and soldered. You basically have to repair this by stripping away a little more wire and remake all the connections. Off course insulate and make good the exposed loom and put everything back as good as possible.

 

Good luck,

Basher...

Great stuff, thanks. When you say in the passenger footwell, do you mean in the well under the seat or in the bottom of the door shut, where the washer pipe lives?
