CAN'T FIND THE CURE FOR THE PROBLEM WITH MY AIR CONDITIONER FAN. I HAVE REPLACED THE FAN MOTOR, AND THE HIGH SPEED RELAY ON THE FIRE WALL UNDER THE HOOD. STILL THE FAN MOTOR SLOWS DOWN MORE AND MORE AND AT TIMES WILL COMPLETELY STOP. THE COMPRESSOR WORKS FINE. WHILE DRIVING SOMETIMES HITTING A BUMP IN THE ROAD WILL REACTIVATE THE FAN BUT IT GRADUALLY SLOWS TO A STOP. I SET THE FAN OUT ON THE TOP OF THE FRONT STRUT AND TURNED ON THE A/C AND THE THING HAD NO PROBLEM SPINING. IT IS NOT RUBING ANYWHERE WHEN INSTALLED. :? GOT ANY IDEAS? I HAVE A1998 SE THANKS, RD

Do you have automatic climate control?

NO, I DO NOT HAVE CLIMATE CONTROL. IT IS THE STANDARD FAN SWITCH HI, MED, LOW, ETC. IT ALL HAS TO BE MANUALLY SET. IF THE FAN IS GOING SLOW WHIEN SET ON HIGH AND I TURN THE SWITCH TO MED, THE FAN SLOWS WAY DOWN EVEN MORE. IF AT THAT TIME I PUT IT ON LOW THE THING HARDLY TURNS AT ALL. AT ANY SETTING LEAVE IT THERE LONG ENOUGH THE FAN WILL NEARLY STOP. TURN THE A/C OFF AND BACK ON AND THERE WILL BE A SHORT RUSH OF AIR THEN THE SLOWING BEGINS AGAIN. THANKS FOR YOUR CONCERN. RD

ALL CAPS = Yelling

Please don't unless you mean to.

AH-HA, THAT'* YOUR-- HANG ON, WAIT A SECOND HERE...

Aaah, much better now.

Okay, the fact that physical bumping of the blower fan lets it speed up tells us that its bearings are shot. When you set it on the strut to test it, I imagine you didn't hold it in exactly the same orientation as the car has it (i.e. vertical mount, with fan shaft horizontal), and the bearings are okay in any position other than the way the car holds it.

You could try spraying its innards with BrakeKleen or something like that to get dirt out, then follow up with a few drops of oil on the bearings. That'll probably make it better, at least for a while (I do this about once a year on our '96 Trans Sport), or you can just say the hell with it and put a new one in.

If you do get a new one, make _sure_ that you can transfer the squirrel cage fan over to the new blower motor without problems. Get the whole installation done and working before turning in the core (i.e. old motor) to get your deposit back.

Thanks for all the help. A new fan motor and no probems. Sorry for the "ALL CAPS LOCK ON" in previous messages. Whew! Touchy bunch.

Thanks again,

I had the same problem and it just finally died. I have automatic climate control. Any thing I should look at first?

If you have the same exact problem, including the fan starting to work when you hit bumps and things like that, then your blower motor is also likely shot.

Yeah, it sometimes comes on when I hit a bump. Thanks.
