Old model 1500w built in 1988. Heater works, fan doesn't. Does anyone carry parts for these anymore. Its a reach I know.

Sounds like the blower resistor. You can do an internet search for a photo. The switch is the object you turn for fan speed.

According to my wiring diagram, the blue and white wire from the blower motor gets power from the key switch. The fan switch and resistor grounds the motor.
No blower fuse is listed.

You go to a Dealers Parts Dept & they will put up a diagram
on screen for you to point to

Auto Parts won't even follow your conversation or have it

More than likely the fan motor its self is short to ground try to unhook the wires to the fan motor and install a new fuse and then turn the fan on with the wires removed and if the fuse is still good you know it is the fan motor its self

Had my blower replaced last year, but my heat does not work. I can turn it up to 91 degrees and it is barely warm. Help please.

Might just have been the right time for the fan to burn out. Buy a new one, junkyard parts are another option, but make sure you test it before you buy it.

You may want to just repair you original motor buy replaceing the brushes in it,any starter/motor repair shop should be able to supply you with brushes that you can make to fit your motor[they are made of carbon so they file down quite easily].

if you are getting power at the fan plug, it is possible that the recycled motor is bad.

Check where the wiring goes into the fan motor itself.The power probably goes there first into a blower motor resister.If the resister is shot many times its the same symptoms your describing.If you dont know what it looks like you could stop at a auto parts store to see.

Jeez, talk about no luck! OK, I'm assuming that the leak test showed no leaks, so that's a plus. Now, when you say it's not working again, do you mean that the system isn't blowing cold anymore, or that the fan that was installed no longer works? I'm pretty sure you mean the air isn't cold anymore, but it doesn't hurt to make sure:)

OK, so if the fan isn't the cure (since it's working), and you had a recharge done, which worked temporarily, I'm wondering about two possibilites - one, that the expansion valve isn't working (this is what allows the freon to actually cool - it releases the pressure from the compressor, allowing the freon to expand. When it does that, it cools). That could be one solution.

The other, unfortunately, is the heater core. If your system routes through there, and you have a problem with it, it could create the problem with the AC. I don't know how Saab does their AC system though, so I don't know if your heater core is an integral part of the system.

An idea - my Audi has two fan switches for the AC condenser fan - a low speed switch and a high speed switch. If your car has that too, and only one switch is functional, it could be that you're not getting the full AC effect. That would be worth checking into.

I'm in Binghamton, NY, the best part of four hours from you.
