Default 97 OBS heater blower quit at the worst time of the year!

I have a '97 OBS with 204K (yes 204K) great, trouble-free miles.

But recently I stared having problems with my heater blower working intermittantly, and finally quitting altogether. With rain and snow in the forecast you can imagine that this is somewhat annoying.

When I move the switch, I can hear the relay "click" over on the driver's side of the car, so my assumption is that it is not the relay (though this may be wrong).

I understand that a new motor is about $120-140 but I cannot find any source of information on how to install one, to even make the decision as to whether to attempt it myself, so I am at a loss there. I don't want to rip apart the dash unnecessarily

Plus I understand that there is a resistor somewhere in the duct-work that could also be a source of the problem.

Can anyone help me with some info about the resistor, or the blower installation? I will probably replace the relay and the resistor, if I can find it, just to be sure that they are not the problems before I go for the new/rebuilt motor. But some guidance and information would be most helpful here.


Thanks,

Ogden

You will see both the fan motor and the resistor pack after removing the glove box. To remove the motor, a reinforcement bar also has to be removed. The resistor pack is inserted into the AC evaporator case and held with two screws.

Hmm, I thought I replied to this earlier but no post.

Anyway, just wanted to say thanks for the info. It sounds like I can probably DIY without too much trouble if I can get some decent weather.

An yet more strangeness...

So I get up this morning and its snowing. No fun without a defroster. So I get in the car and just for kicks flip the switch and the blower starts no problem. There is a "clicking" noise that changes speed as the blower speed increases and decreases but the blower came on an ran all the way through my 1+ hour commute.

Could it be something with the weather? Humidity/expansion/contraction/etc?

Maybe some junk jammed the blower wheel, although it's hard for any large pieces to get through.

After several decently cold days I am pretty sure it's a connectivity issue somewhere in the system. As long as the car temperature is cold, it works, but after the car warms up (even though the air temperature is still cold), it becomes intermittant again.

It doesn't click anymore either. If something was stuck in the motor and interfering it has hopefully worked it's way out of the system.

Yeah, its seems to be working fine, though I won't know for sure until the temperature warms up a bit, so maybe in April?

On the next decent weekend day I'll clean all the contacts I can get to and see if it was just some corrosion or dirt in the works.

I dunno, maybe the car is posessed.
