I just got my car back yesterday from the dealership.  I was WAY out of warranty, but they replaced my condenser for free.  The other problem I had was the fan speeds on my heater-AC was very low, and speed "5" wasn't working at all.  Turns out that a resistor was smoked for the speed "5" problem.  They replaced the resistor, and speed "5" is back.

The problem is that the fan speed, set at "5", seems like it is set at "1".  The AC is working again, thankfully, but the fan speed will not keep up with the heat when it is truly hot.

Does anyone know what this could be.  My wife is preggers, and I'm afraid won't make it with a speed "1" AC.

Any help is appreciated, if you know what relays control the heater blower, or fuses to look for.  I lost my owner's manual a bit ago, and have yet to replace it.

I sure wish they would put owner's manuals in PDF for easy online searching.

Thanks in advance,

Robert

YAHOO group under 'files section' has 2001 and 2002 owners manual in PDF. Here is a link to the 2002 version (if it works for you):

It's possible that the Climate Control Headunit needs replaced. I just replaced mine because it was cycling my A/C on and off... some kind of short inside the unit.

Okay,

So as it turns out... That HEPA filter does do something.  Well, actually, it does a lot of nothing if you don't replace them.  A thought (not that there are many, I probably used up my monthy quotient) popped into my head yesterday saying, "Hey, you haven't changed those vent filters ever, and you have 77k miles on your car.  Could that have something to do with the fan speeds?"

And wouldn't you know it, it DID!

Boy, do I feel like an idiot now.  Oh well, it is fixed now!  Looked at the scheduled maintenance on those filters, 15k miles.  I think I am a bit away from that.

Glad to see it was something as minor as the filters. I guess I need to check mine and see if I even have one!!

How often should they be changed (in normal usage)?

Is there an aftermarket source for them, or do you have to get them from the dealer?

You can get them at most auto parts stores. The dealer will of course, gouge you so I would avoid them. Purolator makes good filters.
