bigal55 Posted August 6, 2013 Share Posted August 6, 2013 Hi all the fan now only works on max, intermittent for a while on 1,2,3, now only 4. i.m assuming it,s the switch, any other ideas welcome, i cannot find how to remove the panel to check switch, sugestions welcome. thanks Alan Link to comment Share on other sites More sharing options...
euroserv Posted August 6, 2013 Share Posted August 6, 2013 Hello Alan, The first thing to check in these situations is the heater resistor. It is almost always the resistor (under the heater fan housing) and not the switch although failure of the resistor can cause a lot of heat near the switch and melt cables and other plastic parts. I am working on one such van as I write. Hopefully yours will be just the resistor. I should add that this is not an exclusively Fiat thing; all vehicles except those with climate control have a resistor to set the fan speed and they will eventually pack up.

I had exactly the same problem about a year ago, and a section of wiring was burnt. I feel fortunate that I took it to the garage when I did. I had a new fan and a section of the wiring. Hope yours is less extensive, regards alan b Link to comment Share on other sites More sharing options...
johnnerontheroad Posted August 6, 2013 Share Posted August 6, 2013 Would this apply to my 1997 Fiat 2.5td or could it be the switch? Alan sorry for high jacking your post. Dave Link to comment Share on other sites More sharing options...
JonMac46 Posted August 6, 2013 Share Posted August 6, 2013 On my 230 if the resistors fail it only works on the highest setting. Full 12V there and resistors drop the voltage for the lower settings. Link to comment Share on other sites More sharing options...

bigal55 Posted August 14, 2013 Author Share Posted August 14, 2013 Update, decided to check the wiring and multiplug with my avo , all ok, so not the switch or wiring, plug the mutiplug back in and the fan works on all 4 settings.The plug seemed to be in correctly before i removed it but it must hve been moved out of position by a big foot, wife of course, :D , as it is exposed in the passenger footwell. thanks for all the advice.
