I have a 2004 xsara estate with air con

 

The blower motor does not work.

 

My wife had the car away for over a month when the fault developed. She tells me the fan just stopped working, but came on sometimes when she went over a bump, then ceased completely.

 

I have little faith in my wife's recounting of problems, but this is what she told me. She has no knowledge of what appears to be the common 'full speed' resistor problem.

 

I have read a number of posts about older xsara and zantia fan problems but I am not sure how many of them apply to my car.

 

I will describe my diagnostics so far and would appreciate if anyone could suggest what further testing I can do:

 

Engine running

2 pin plug with heavy red / black wire plugged in. Check for 12v+ and 12v- both Ok (no 12v+ when ignition on but engine not running)

 

Check for 12v+ at red cable on 4 pin plug going into motor - OK

Connect a test bulb (screwdriver) between earth and yellow wire on 4 pin plugs - a relay clicks, but nothing else happens

 

When engine running and fan rotary switch turned to approx 3/4 distance, a motor on top of heater unit opens a flap on top of heater unit.

 

Any suggestions welcome
