Customer Question
My 96 f150 4.9...

My 96 f150 4.9 when,I start the engine with the a.c. on ,the compressor only runs for about 10 seconds and stops and will not start again until I restart the engine

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

No

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

I've changed the low pressure switch on the drier

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

That's it

Start the engine with a.c. switch already on
Ford Mechanic: David Craig, Auto Mechanic replied 11 months ago

so if you start the engine with the ac off, it starts fine and then when you turn the ac on its fine?

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

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.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
