Rock Posted November 20, 2014 Share Posted November 20, 2014 Does anyone know the location of the resistor? My blower works on all speed except high and I think this is the problem but cant find were it is at. and anyone know what the part # is?

stangeba Posted November 20, 2014 Share Posted November 20, 2014 A/C or non A/C? Here is a link to two pics of my NON A/C resistor block. I believe high speed by-passes the resistors and on A/C cars, there is a high speed relay. https://picasaweb.google.com/lh/photo/yFpOynlWmRufNyEGts_X49MTjNZETYmyPJy0liipFm0?feat=directlink https://picasaweb.google.com/lh/photo/D0Dhg5idQ3IMYDbmx3QRo9MTjNZETYmyPJy0liipFm0?feat=directlink Bruce Quote Link to comment Share on other sites More sharing options...

lastss Posted November 20, 2014 Share Posted November 20, 2014 at pass side cowl area just were the wiring tube ends or inside it at the end is a 30 amp fuse for high speed blower only bad fuse or connection. Quote Link to comment Share on other sites More sharing options...
Rock Posted November 20, 2014 Author Share Posted November 20, 2014 The relay is the one on the firewall by the a/c box? There are 2 relays I believe. what color wires am I looking for? Quote Link to comment Share on other sites More sharing options...
lastss Posted November 20, 2014 Share Posted November 20, 2014 Not a relay High speed blower is only direct 30 amp circuit on a 71 a White fuse holder with orange wire black wire other easy to spot top of evaporator case at the firewall.

Rock Posted November 20, 2014 Author Share Posted November 20, 2014 I looked high and low and found no in line fuse for the large orange wire....I did find the resistor pack but doubt it is the problem now.that large orange wire goes to the relay though....could it be the relay on a 1970?

BigdaddyT Posted November 21, 2014 Share Posted November 21, 2014 Wow! I had no clue what that inline fuse was for, learn something new everyday Quote Link to comment Share on other sites More sharing options...
