Fan switch

Somewhere in the last week or so I found an article on a site about fixing the fan switch by replacing an elctrical part on a small board near the passenger's feet. Could have sworn I saved the link, but can't find it on either puter. Does anyone know about this article or anyway to find the cause of only having High and Off working on the switch? I've already checked the unit itself and can find nothing wrong. I also picked one up at the yard for a buck and I get the same results. TIA

Radiator fan or HVAC blower fan? Which one are we dealing with, and what is the issue you are trying to fix?

5-90

The part you're thinking of is the resistor pack.

Thanks Eagle! 5-90, it's the blower switch for heat, A/C. I really need to put a sig together. I run an 84 and it doesn't have an electric fan. The article gave the value for a small resistor with a point that you can get at Radio Shack and solder in to replace the one there. Supposedly this fixes the problem of only having Off and High working on the fan switch. It also gave a way to test the one on the original using an ohm meter to test if it's bad.

Update

A few weeks ago I started this thread in hopes that someone else had this link stored since I couldn't find it. Well, here is the repair of the heater/AC fan switch if you only have HI speed. Hope this helps someone else.
