blower motor issue

[diabloam]

Got car back from being resprayed after I had fitted new sills (will update my how to post on that when get photos off camera). Despite being off road for 8 months and only doing 20 miles in that time, it passed MOT with only advisory on front discs (Need to overhaul brakes at some point, think I got plate lift also). Anyway great to have car back on road, missed it. However I cannot get my heaters blowing, which in Winter in N.W. Scotland is a problem, lol.

I played with the relay and fuse, seem fine. Neither the demister button or the blower speed dial (on any speed) seem to start the blower, I am not sure what is wrong. Left the demister button on(This normally puts fan on full (4) and heat directed to the windscreen vents) whist driving and it came on once when I was turning a corner, and stayed on until i switched it off. Then back to not being able to get blower going.

Since my car has the air con is the blower not coming on cause of the automatic cabin temperature control or something, or do I just have a dodgy connection or knackered blower motor or something along these lines, is there any known problem areas.

Searched forum but cant seem to find anything similar to this. Any suggestions on where to start if anybody has seen this problem before, would very much be appreciated as its stopping me using the car for short journeys (Windows clear eventually with just the through flow from the vents but it takes ages), thanks all

No suggestions from anybody? Also does anybody know how the front of the heater panel comes off? cheers

If it still doesn't work on position 4 then the resistor pack can't be faulty. As the demister doesn't seem to work normally either, I would suspect a short somewhere in the control panel or a loose connector. Perhaps damp has made its way there as the car has sat long and cleaning the connector may help? If I remember correctly There are two connectors for the control panel. Can you still hear the small electric motors when moving the two horizontal adjustments?

I feel your pain, I have what seems to be the same problem albeit intermittently.... To remove the temperture control unit, you take off the knobs (carefully!), and then gently prise the plastic cover off. Then there's 4 screws to take off and you can pull the unit out. Go here to everybody's friend Clark for tutorial: [link=http://www.clarks-garage.com/shop-manual/body-08.htm]Clicky![/link] The connectors have clips so it's unlikely that they came loose, but if you want to try it doesn't take very long, but it's probably not the control unit. I swapped my control unit with another I had in another dashboard I had, and it worked fine when I tested it but alas 2 days later we were back to the same! I might recheck the fuses and relays again, but I don't think it's there. For me if it works when I start the car it'll keep going without problems, but the next time I start it might not, and then it's like we don't even have a heater, no electric motor sounds on adjustments, nothing. Might be the motor packing up, and it just isn't starting sometimes. Not sure, I'll hopefully get some more time over Christmas to fiddle with it.

No words of wisdom here, but if it came on when you were going 'round a corner then I'd probably suspect a dodgy connection somewhere. Snag with that is that you could be chasing for a long, long time. Try looking for power at various points along the circuit - probing through the wire covering, if need be. Oli.
