air conditioning fan not working
Posted: Tue Apr 30, 2013 12:41 pm
My a/c has finally stopped working any ideas on getting it sorted
History
Btw it's the older manual set one not a digital one. The unit was
was working on all switch levels apart from full (4), So i tried a new fan resistor (no change), then was on a long drive and could smell plastic type burning smell. a/c now no longer works in that the fan no longer works - I have put a manual switch direct to the fan and this works (full on or nothing) as it should.
The a/c hot and cold actually works it's the switch that does not. I have taken the rotary switch off and tested it it works?
- I also took it aprt and nothing burning. So i must conclude it must be some wire looming?
I have replaced the fan resistor with a set from another bongo when it was working before and this did not alter the a/c working - still would not work on 4
just wondering what's causing the problem and any solutions, any ideas
I can verify the switch and the fan resistor works ok
if there is not a straight forward solution i might consider a variable resistor (rotary to regulate the fan from the bonnet) I would just set to sensible value (cool but not noisy) and leave. would anyone know what wattage it would need to be? I am guessing the fan can take alot of juice judging from the sound of it.
