Thanks all for the assistance I am still struggling to solve this problem.
I have tried a cigarette infront of the little vent on the module and it does pull in the smoke so the fan is working. I have two more questions before I submit defeat
1 = can low gas in the air con cause heating problems with climate control, does the heat and cooling work together.
2 = If the sensor in the module reads open circuit will thi not bluff the system into thinking the car is allready warm. If both the questions are false I give up have to take the car in $$$$$$$$$$$$$$$$$$$$$.
