Customer Question
I have a 2007...

I have a 2007 F150 5.4. On Thursday my ac stopped working. Compressor won't engage. On Friday the truck won't start. Battery is good. replaced starter still won't start, replaced neutral safety switch, still won't start. Jumped from ignition switch to starter , can at least start truck now. Is there a ground issue that would affect both starter and ac? It seems odd that both would go out one day apart.

Mechanic's Assistant: Have you checked the battery, particularly the terminal connections? Are they corroded?

No, battery is fine.

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

The ac compressor won't engage and replaced the starter and neutral safety switch. Yes trying to fix myself

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

Like I said, it seems odd that both went out within a day of each other. That is why I trying to find out a common connection or a ground issue.

I replaced the starter, the original wasn't bad. I replaced the neutral safety switch, it didn't appear to bad either. could the ignition switch be the problem?
Ford Mechanic: David Craig, Auto Mechanic replied 9 months ago

I wish I can say yes, but we need to est a few things first.
