hi guys, i bought my daughter a 05 1.2 clio and the heater motor seems to only work when the car is driving. i took the bit of plastic off where the wipers go and if i give the blower a little nudge it comes on. im not really savvy with this kinda stuff but have seen lots of posts on the subject. could this be just the motor that has went or could it be several other things. ty for any replies
