Hi Hope you guys can help me out as you have been brilliant in the past. I have a 1.4 16v 2000 Astra that has had a wierd problem since i bought it secondhand. The issue is that the heater fan sometimes stops working at all speeds then will randomly work fine for weeks at a time then stop working again. Another thing i have noticed related to this is on a recent long drive the rear window heater failed along with the fan ie no light came on to indicate it was working and no relay clicking could be heard. On turning off the ignition then turning it back on again they both sprung into life and worked fine for the rest of the journey. Are the two problems linked? On a note there is no air conditioning. I have checked all fuses and all appears fine there. Can you advise where to start looking as i do not want to hand it to the dealer and them take £50 to look at it and say "we cant find a fault"! Any clues/ideas what to check would be great as this is really annoying and am unable to find anything related to the problem on the web. Is there some sort of circuit breaker which cuts in if there is a fault or gets to hot? Is this a known fault?
Any help would be great
Thank you in advance
