‘92 OCC BLOWER

The OCC i picked up about 9 months ago has been great. Today i had my first issue. No blower. According to the owners manual the AC/Blower sre controlled by the 30A fuse in the #7 position. I checked it, and there is no fuse there?? Should i try putting one in, or is ot possibly empty for some reason?

I'd put a correct amperage fuse in. Definetely needs one to work.

Also was the AC blower motor ever working and suddenly stopped or it never worked?

The funny thing is the blower was working fine when it suddenly stopped. That’s why i was surprised when i checked the fuse in what is supposed to be for AC/Blower spot and there was none. To make matters even stranger today the blower and ac is back - still without a fuse in the #7 spot

Weird. That fuse space is for electronic air conditioning power. Does the car have automatic temperature or the manual control? You may not use that fuse space with manual a/c but beats me.

You’re probably right. I have the manual control. I guess the next thing to check is the blower motor itself

The manual AC has a resistor pack in place of the transistor speed control for the automatic AC.

I replaced the resistor pack. Still no fan

Did you check the fan itself?

Yes. Its the fan itself. Hooked up the connector to a good blower i had and it runs fine - even changing fan speed with controls. Now, all is need to do is change it out, but i can’t seem to get the old one out. I removed 3 screws from the housing, but it doesn’t drop down Feels like there may be at least one more screw in the back that i cant see. It’s really tight back there. Does anyone know if there is a fourth screw i cant see?

Looks like three.

Thanks. Maybe there is just to much other stuff there to get it down I’ll try again if it stops raining here. Very crowded down there. Not sure what can be moved

There are a couple of wire bundles that go under the fan . You must move them out of the way to get the fan out.

Yeah, the only thing it says to move out of the way is the electronic control module and retainer, must include those wires too. If the motor has a seal or gasket it may be a little stubborn to remove.
