I have a
2003 Chev Silveado 1500
Manual Dual Climate Control W/Rear Defrost

I've lost all my blower fans speeds except High (#5) I changed the climate cotrol module and it didn't solve my problem. What other part should I be looking to replace?

I have no information relevant to your particular quandary. I do, however, have many questions about the hellish noise emminating from my blower motor. The thing squeals like a banshee on any setting (except, of course, OFF), and it's driving me nuts. So much so, that I often carry on and carry forth driving without any heat in the winter, or A/C in the summer.

I could rip the thing out, and replace it, but I'd like to know beforehand if anyone else has done this only to find that their problem went unresolved.

Silva...replace your blower motor and all should be fine. probably have a dry bearing
