The heater/AC blower fans are not blowing at fast speed on my 82 Spur. They are blowing perhaps at medium speed. Both are blowing. This is true if I choose "high" overriding "auto". I tried to find the blower relays near the firewall, but I do not see them. On the passenger side, I have the relays for the wipers;on the left side, there is the horn relay, headlight, etc. Any guidance what the problem is or where to find the relays is appreciated! PS Seem like I remember there is a blower fan module somewhere???? Richard | ||

There is a fan speed module part number UD 22295, try cleaning the connector pins up first as the replacements are not cheap This may give some guidance https://www.youtube.com/watch?v=drnbIom114E Its a bit slow before pictures come up | ||

The relays are just behind the LH front suspension tower on my 88 .There are 4 relays for the 4 speeds and an overall relay .The fan module is just behind them on bulk head .Tested the voltage of each speed at the fan and found there was a significant voltage drop at fan high speed should be 12 volt but mine was 7.5v .My electronics expert tested the relays and said although working the contacts were poor causing voltage drop .His answer was replace all 5 relays and this solved the problem. Original relay number was 0332204122 and is replaced by Bosch number 0332209152.My electronics friend said this problem can also cause slow windows. | ||
