AC Fan speed problem

[modelt609]

87 Turbo The AC fan will only work on low and medium speeds-changed the resistor and the fan relay and still same problem- any thoughts on what next- could it be a switch problem and which part do I change next?

There are complete AC /Temp control units on ebay but you never know their condition. Thanks for the reply

Sounds like the actual switch on the AC/Temp control panel. Might have to take a chance on one off ebay.
