Car Forum / Porsche / Porshe 944 / August 20071983 944 Fan Not Working / Overheating
My '83 944 was running very hot today. Even though the weather was warm, it is unusual for her to get this hot. When I got home and popped the hood I noticed that neither of the fans were running. The a/c unit needs a charge so I'm not sure if the one fan will ever come on. In any event, are the fan relays known to go bad? Is there some simple check I can do to test the relay? Can / Should I jump a few contacts to verify that the fan works? Any other thoughts? Cheers! Most likely the thermo switch. Go here and read about it: http://www.clarks-garage.com > Most likely the thermo switch. Go here and read about it:http://www.clarks-garage.com Thanks! I didn't think it would be something as simple and quick as swapping in a new relay... Never is.... =( Its going to be a while before I can get to this problem. Can I rig something up with the relay to turn the fan on manually? Turn the air conditioning on. If the fans are good they will run all the time with AC on. Will the AC switch turn the fans on even if the compressor is not working? The system has been low (or empty) of R12 for many years... Thx > Turn the air conditioning on.

I can still spin my fans by hand. Is it safe to assume that this means the bearings are still good? Thx again for the advice! I picked up a new thermo s/w and relay and hope to have them in soon... > so far in the last couple of months I've found two fans with seized front > bearings, both cases the LH fan. suggest oiling the bearings once every 20 [quoted text clipped - 25 lines] > > - Show quoted text - fans should spin "easily" by hand, if one is much stiffer than the other, it's a bad sign I'd still encourage you to oil the bearings as a preventative measure test fans by applying power directly to them > Gotcha... > [quoted text clipped - 10 lines] >> >> "York" <Notchap...@aol.com> wrote in message SignaturePosted via a free Usenet account from http://www.teranews.com |
