Surveyor Posted December 21, 2020 Share Posted December 21, 2020 Yup its the mechanical novice again, I have an issue with the heating, think its totally gone, I have been advised to test the fan by short circuit to a battery. Looking at the parts manual and looking at the system its unclear to me how to check which wires are the ones to wire to the battery, at this point I don't want to go to a garage, can any one help, Quote Link to comment Share on other sites More sharing options...

Richard Farrant Posted December 21, 2020 Share Posted December 21, 2020 First thing to check is the fuse! Quote Link to comment Share on other sites More sharing options...

sirhc Posted December 22, 2020 Share Posted December 22, 2020 The parts manual won’t tell you which wires to test, you need the wiring diagram for that. Quote Link to comment Share on other sites More sharing options...

Good point, i dont think it is but will check, we were driving along and a bang happened, left hand door shock a bit, checked engine all okay, then the dash board lights started to mist up so went to the thought of heater, the controls have been jammed so it was on my to do list Quote Link to comment Share on other sites More sharing options...

True, I will ask around and see who has one but Ruxy with his colours has given me a start which is appreciated Quote Link to comment Share on other sites More sharing options...

ruxy Posted December 22, 2020 Share Posted December 22, 2020 No rotation on any speed , motor jammed or blown fuse. Single speed (fastest) only operation , could be resistor blown. Switch could be gone but I doubt if on both sides. Have you checked the fan will actually turn - leaf mash is a common problem on many cars. If stalled it will blow the fuse.

Ruxy Not tried anything yet leaf was something I had not thought of, the thing stopping me starting is the fan appears to be rivited to the heat exchange unit, I think I start with the basic, I do see I may have to take the windscreen wash bottle off to get to the unit Quote Link to comment Share on other sites More sharing options...
