I checked the fuse its a 25 amp and its good. What else is there to check. The relay? How much does a new blower cost. I turn it on and it doesnt work is the prob.

This may sound silly, but have you checked the connection at the blower motor. I have a Grand Am that gives me a little trouble every once in a while. The connection at the blower motor was corroded and loose. Use some emery paper to clean it up and stick the connector back on it.

I dont rally know how to get to the blower. The camaro they took the stock motor out and put in a 350. I think they didnt hook it up but I dunno. I can hear a kinda pressure changing sound. I think is the ac. I have no ac beucase they took it out the tank that is.

Thumbs up

They are!

I am thinking of something. If I hook a volt meter upto the pos and neg of the blower motor. See if there is any current. If there is some I know the blower is bad. If there isnt any currenct it can be the relay or broken connection. Anything else to add? I am not sure what the blower resistors are!

The blower resistor mounts to the top of the evaporator housing (in the engine compartment) with two screws, toward the inboard side. Check continuity across all terminals (4 or 5 wires in connector)- if you find an open, that's why you have no power to the blower motor (check motor first for power - if you have power at the motor and it doesn't run, it's blower motor time).

Ok its not the blower it self. I hook power up to it and it spun and shot air into the pass cabin!

Ok is the blower resistors a little black box ? When you pull it out it has like 5 prongs comming out?

ekg, the black box is the relay, the resistor bank is in the evaporator box and has a three or four wire connector on it and when you take the two screws out of it, it looks like springs that are wound sideways. Hope this helps.
