Customer Question
I have two issues...

I have two issues since having my truck serviced for exhaust manifolds. The a/c does not work and the radio is powered on but no sound.

Mechanic's Assistant: Have you checked the fuse?

Yes, all of them

Mechanic's Assistant: What is the model/year of your Ford?

2004 F150 lariat

Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far?

Myself now. The shop replaced the ac compressor but still don't work. Showed me on the diagram that he tested all relays and compressor would kick on. Told me the pcm must be bad????

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

The radio has the antenna wires connected and it's not the mute button

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
