Hi Guys,
I have looked and didn't find the solution to this problem. My A/C Blower motor quit completely this week. I have had the Blower control Module and the Fan Motor replacewd twice in the past three years. This week was the second time. The problem I am currently having id if the setting is on Auto, the fam rund fine for approximately 30 minutes, then it starts changin irratically from high to mid range then back to high. The repair shop checked and said the control Module and Fan motor are fine. They said if I left it on Manual Fan control, it owuld be fine. They said it needed to be scanned in the HVAC Programmer, but they didn't have the scan tool. Any one else had this problem, and if so, did you find the problem? All help is greatly appreciated. Thanks Guys!

The blower on my 97 acts up as well. It went out last year and I played around with it, cleaned everything all up and then it started to work again. Just a few weeks ago it went out again. I still haven't found the cause.

Thanks Dan. If I find the solution, I'll forward it to you!
