Default Front Blower Intermittant Problems

Hey y'all!

OK. 1999 Quest. Replaced the resistor for the front blower motor controls as it was either off or high. Now all speeds work. Sometimes. Other times the motor does not respond at all. I thought it might have some blockage that was resisting it's turning as it seemed to work a couple times when I kicked the housing, but that only worked a couple times and more often does not. Sometimes it just decides to work - usually when I just start the vehicle, but that correlation is anything but conclusive.

I was thinking of trying to open the compartment up and prod around, but prodding around is exactly what I would be doing - I don't know if I can easily open the compartment that houses the blower assembly up, and even if I can, I would be shooting in the dark.

Anyone have experience tracking down this kind of problem? Is it possible (God forbid) that some darned electronic module is causing the intermittent problem, or is it more likely a mechanical problem? If an EM, I am really in trouble.

Please advise, as cold weather is on it's way! I don't care much about a/c, but heat is rather important here in Colorado Springs...

Many thanks to all of you for your help.

As you can see from the attached diagram, the circuit is very simple and if the resistor and fuses are OK (Fuses OK since it works at times), then more than likely the problem is the blower motor.

MUCH appreciated!


p.s. Is there a resource that I can access these diagrams?

Besides wishing to know if there is a place I can access electrical diagrams such as what you provided, what might your thoughts be on those blower motor relays I see in there? With other older electrical systems I would occasionally find corroded contacts either not making a connection or sticking together. Are these in one of the fuse blocks by any chance?
