Replaced blower fan resistor, now....
I recently replaced my blower fan resistor in my 07 Chevy
trailblazer because when I shut off the car the blower fan
kept running. I had to strip the wires on the original three
wire harness connector that leads to the control unit, and
because the wires were to short on the replacement part I
had to used the old blower fan connector, strip those wires
and connect them to the harness lead in wires for the
resistor module.
Once completed, I started up the car and tried running the
AC but now the blower fan won't run. Any ideas?
Assuming everything was wired up correctly, make sure you got the right part. If you have automatic climate control, it's a different part, and not called a resistor, it's different than the actual blower motor resistor that is used for the manual controls. Both parts look similar, but are different. On a side note, the old blower fan connectors tend to melt inside, shorting it out.
Yeah, I really feel everything was hooked up correctly. But now you've got me thinking perhaps it was the wrong part. https://bit.ly/2OAxAhl this is what I bought and installed, but I believe that https://bit.ly/2OAMAvS this is what I need. However, when the part was going bad and not shutting off when the car stopped, the fan also was acting weird, but coming on full blast and then slowing down, would the fan control module (or resistor) cause that? Or is that a blower fan thing?
Do you have auto climate control? The part for the auto climate control is called blower motor control module IF I recall correctly. But must specify before ordering. I'm thinking it's still your main cause. Look at this I pulled off of rockauto.
Yeah I have auto temp control. What you're saying makes sense. I'm going to get the blower motor control module, and then go from there. I'll post back the result on here so if anyone else comes across this same problem. Thanks for the help.
