97 Astro van, 117,000mi, 6cy, 2wd, blower motor problem


#1

My blower motor quit working in the high position today. It works fine in the other positions. Looking at the Haynes manual it looks like there is a relay and resistor for the high position and only resistors for the lower positions. Can someone tell me the location of the relay and resistor pack and how to get to them?


#2

It sounds like the high speed fan relay is the problem. If the lower fan speeds work, there’s not a problem in the resistor block.

Isn’t there a section in the manual that describes where the relays are located? If not, and there’s a local library nearby, most have free access to ALLDATA website. Here it will reflect where this relay is located.
