Climate Control Problems - are the blower and final stage resistor the only parts?

[SunnyC]

Hey Everyone,

I've encountered an issue with a 98 328i blower / final stage unit problem.

The blower motor stopped working so i changed the final stage unit(resistor) and it worked find for about 3 days. Then it stopped again. Recently hit a bump and it came on again but hasn't worked since.

Is there anything between the Blower Motor and the final stage resistor and the electronic climate control that I might be messing?

I don't wanna blow a few hundred by "guessing" it's the blower motor (cuz i've already tested the climate control in another car and replaced the resistor with a brand new one.

Any thoughts?
