Check the heater module by the fan in the duct work. They crack in the bottom inside and quit working. Done 2 of them recently myself.

now that I have screwed around with it ,the fan comes on but only once in awhile ,doesnt seem to matter when , like it has a mind of its own. Would this heater module cause this ,and the connecter is tight for the fan

I was wondering if you figured youre problem out. I have the same problem. I replaced the blower motor on my 95 and it works some of the time.

Did either of you find out what was the problem? I am having the SAME exact issues with my blower motor. What have you found out?

My problem was a faulty ground wire. I ran a new wire to the strut tower and my problems went away. Then I sold the car.

I had the same problem on my 94 STS.
The connector to the blower motor sometimes does not make the connection. Try pushing it in by hand and see if the blower goes on. If that does not work try bringing another ground to the black ground wire. After I got another blower motor from a wrecker I found out my old blower was good but the connection was bad. I put an elactic to keep it together and it works fine. Anyone want to buy a blower motor ?
