Advice? Fan stopped while heater was running. I detect heat when vent setting on with a small amt. of airflow; but the fan is not working. There is no airflow at all when air set to internally recirculate. I checked fuse and changed the relay. No luck. What next :screwy: ?

I would check if you are getting power to the blower motor. Or try to wire it directly to the battery.

:screwy: I'll try to direct wire it next, I reckon. After I get outta the ER where I work that is! Thanx.

I have the same problem. How would you go about wiring it directly? I assume that you need to first take it out from behind the glove box but if there is an easier solution please do tell. Thanks!

I gather that it doesn't work at any speed setting, correct? If that's the case, it is not the switch.

You're right, it does not work at any speed. However this morning I went to the local auto wreckers and pulled out another heater blower assembly and tested it on the wiring and it worked so I put that in. When I get some spare time I will look at testing this with 12V direct and possibly pulling it apart to rebuild in case this currently working one fails. What a pain to put these back in though! Thanks for the reply!
