2008 Lonestar Ac problem

Just taking a wild guess, I know nothing about that system, it could be low of Freon, & the pressure switch will not allow the compressor to run.

 

A/c is computer controlled. You are totally flying blind with out the right tools. All you can do is throw parts it. I suggest you take it to the dealer.

 

Might still be a pressure problem.

As Heavyd said, 'Your flying blind.'

Don't know if its safe to hot wire the pressure switch or not, if you did that you might find out something, but as I stated, might not be safe on newer equipment.

 

Ok, man, there is no way to know why the a/c isn't working electrically unless you have access to dealer level diagnostic software. These use a high pressure sensor, not a switch. Thermistors do go bad and so do high pressure sensors. There is also wiring and connectors that could be your problem too! I understand not everyone wants to go the dealer. But you are just going to have to replace whatever and hope to get lucky. What happens when you have a pile of time wasted and replaced parts you didn't need to? That sounds like a bad experience too! Good luck!

 

He will have a parts store to fix the AC on that truck, yet by the time he has another AC problem he will be in a different truck.

its not as it use to be, they used to be quite easy to fix, but as you stated, you now need the computer that the shop has to diagnose them. Us shade trees are mostly useless on modern vehicles.

With that said the Freon could still be to low to let the compressor run yet still blow cold air. Not saying it is, just that it could be.

 

Yep, thats right. That is why is it so important to have the right tools. Pressure gauges are also a must.
