Really frustrated over this, and I'm guilty of throwing parts at a problem I don't fully understand. A few years ago I replaced my resistor pack with a newer style GTS part. I re pinned it as instructed and it worked fine, all speeds worked. Recently only high speed works, any position of slider. So I replace the blower motor and clean the resistor pack. Works fine the first time I start it, at all speeds. A few hours later I start it again and only have high speed. So I order and installed a rebuilt head unit today. Zero change, still high speed only.
I have a volt meter but I'm not very good with it. I don't understand what the problem is. Seems like a resistor pack but I don't know how that works or what to look for. Thanks for any help.
