Welcome to the forum, did you check the power window circuit breaker? Should be in the relay module, under passenger side of dash. Can't post circuit breaker location, something isn't working. I'll try later.

Anyway, pull the relay, use a testlite on terminal where relay plugs in, the circuit should be hot, with the key on.

number 25 should be power window circuit breaker.

Sorry it took so long to get back to you but I tried to find the power window relay under the passenger dash but I took the cover off under the glove box and the only thing that is under there is the venting for the heat. If I'm missing something let me know and thanks for the help

Hi, maybe this info will work better?

Ok I got the glove box out and found where you were talking about and I checked the two 30 amp circuit breakers and one the test light comes on nice and bright and the other is only real dim so I don't know what that means.

The last diagram I posted says 30 amp fuse. My data base seems to contradict itself. I don't know if it is fuse or circuit breaker. The terminals of the fuse or circuit breaker that you suspect, the terminal that isn't hot, check the continuity between that terminal and the proper terminal at the blower connector, If there is good continuity, then you found the proper circuit protector. It's just an ohms test, if you using a meter. Can't be voltage on either circuit, during testing.

As far as circuit protector ie fuse. One leg is voltage to the fuse. The other leg supplies voltage to the circuit the fuse protects. So with the fuse unplugged, one terminal is hot, the other isn't.

Another thing you can do. Take the connector loose from the blower motor, use jumper wires from battery for voltage and ground, use inline fuse, touch to blower connector, see if the blower works. If it doesn't, faulty blower motor.

I will check continuity but I don't believe its the blower motor itself because all of the power windows stopped working and I noticed that the airbag light is on but will go off if I move the blower lever to off so theres something going on in there I just don't know what it is.
