Hi All,

Need a little help with my AC/Heater fan switch. It only works on High. No low or medium speed fan. I have checked all the fuses and I think checked all the gounds but nothing. Am I missing a relay or a fusible link somewhere in the loop? Any help in pointing me in the right direction will be appreciated. Thanks for any and all input.

Thank You to Ken...I replaced my 4+3 relay today and wired my switch and the car drives and shifts like a dream....will take time to learn when to switch into OD.....but that's the fun part of the car.....drivin it!!!

PS. In case you are wondering 'Top' is slang for an Army First Sergeant......I retired in 1997 after 21 years...

Funny you should mention the thing with the fan (blower) switch... :gap

I had the same problem; I replaced relays, switches, and everything else I could think of, then I discovered a loose connection similar to the problem I had with the battery connection to the distributor.

The relay on top of the blower moter under the hood had a loose wire at the connection in the plug; that's why, in my case, I could get it to work when I played around, removing and replacing different things in the hunt for the solution. It also explained why the thing would work then cut off intermittently. Frustrating these cars can be! :D

Try that and see if you get all three blower speeds. ;)
