Betsy Posted December 6, 2008 Share Posted December 6, 2008 Friend has a 300tdi with inop heater blower. He says it was intermittent, then stopped completely. Checked fuses and all ok. Looking at the haynes, there are a few bits to look at, such as the switch, relays, air con control unit etc. Is there a common failure point to look at? any advice welcomed.

Richard Mills Posted December 6, 2008 Share Posted December 6, 2008 Hi There, Easy one this... passengers side footwell, remove plastic cover from side. Under this at the bottom is a multiway earth tag. You will find the earth for the heater and other things is burnt brown. Cut off the offending spade and wrap the wire securely on the bolt post and tighten the nut over it. The spade is designed to carry a maximum of 10 amps, this circuit can take up to 30. Design flaw here. Quote Link to comment Share on other sites More sharing options...
