Can someone please tell me how to inspect the heater control module on my Pug205 (K reg.) to see if it's faulty? The blower comes on sometimes but usually it doesn't work and I need it to de-mist the windows. The Peugeot Dealer told me that I probably need a new control module but it's over £100, but he also said it could be a bad connection (fingers X). Someone told me that I get to the heater through the passenger side-well but I can't remember how or what I have to disconnect? Thanks for any advice?
