Question about 2003 Pontiac Grand Prix
I replaced the motor and resistor now seems not to be blowig very good not as powerfull as the old one any suggestions
The only thing that is now coming to mind, with that information, is that they may have given you the wrong blower motor resistor (putting too much resistance in the circuit and thus causing the motor to run slower) or the motor itself is going bad (not common in that they go bad that way, they usually just fail) or your ignition switch is getting a lot of carbon build up in it.
GM runs the power through the accessories through the ignition switch and the heavy load causes carbon build up on the switch contacts and can cause issues. Commonly, however, when that happens, there are issues with other accessories such as the radio, Drivers Information Center, etc.
Theres no easy way to test if its the ignition switch or the blower motor itself that I am aware of. So I suppose the next question would be did it have this exact same issue before you replaced the blower motor resistor.
Also, if you like, there is a Grand Prix community online at www.grandprixforums.net that may be able to offer further insight if you want to sign up there and see if you can get further assistance from there.
