AC/Heater fan switch

[Mike Gaskins]

The high fan switch quit working, low and medium still work. I purchased a new AC/Heater control (entire unit) and the high fan switch still does not work!

Any ideas?

Mine did the same a while back. I found that the high speed fan power is fed off it's own wire which is thicker and is connected with the square connectors at each end. The location of the connector was being jammed to the left of the fan housing by the passenger fender. My connector was jammed and after driving over a few bumps it would make a connection and then loose it the next day. Check that out it's probably disconected.

Two wires are in the connection. Large red and a small green wire.
