AC problems

[keithgonzales]

I am having problems with my 99 F250 super duty's ac. My controls are not working. I changed the blower motor switch and the master control switch. But still nothing powers up, defroster, AC, or heater. Is there some other relay or switch I could check and where is it located?

From here its no brainer stuff, fuses, grounds, etc. Are you getting power to the switch?

fuses are all good and wiring all appears to be good with all connections tight. I am getting my test light out to check for power. I worked with it today and now am getting power to AC clutch.
