I have seen a lot of threads on the problem.
I was able to smack the dash and have the blower come on. Or sometimes it worked normally. I believe there is a relay in the resistor unit. Getting to it is gonna be fun as it is next to the blower and under the dash wedged in near the firewall. I saw a video on You Tube so I know what I am up against.
Another explaination in another forum suggested that a connector marked C-12 or C-21 (or something like that) may have a loose connection. That means yanking the radio to get to.
I want to know what is the best way out to get my A/C on again. And the cheapest. Saving gas with the air off but it gets damn hot and humid here in Texas.
Thank you for your advice...............
