The drive side & rear A/C blow warm while the passenger side blows cold. I have recharged it & it seemed to work for about a month, now back to warm. Can somebody tell me what to try next? I've been searching the web & going in circles!
It sounds like you have a freon leak. You can buy freon that has die in it so that you can find and fix the leak. Look for freon leak detector. You charge up the system with a can of leak detector, then top off with freon if needed. Run the truck, and look for leaks. This may take a while to show up, if your lucky, this meams a small leak.
