My a/c worked fine at midnight Sat/Sun, Sun morning about 10 am, truck turned on, turned a/c on, compressor will not turn on, light inside says it is, but its not turning, so the truck is blowing scalding hot air? how do I fix this?

You probably have lost all or most of your freon and will have to recharge the system. A gotcha is that the on board computer has locked your compressor out with a code that has to be cleared before your compressor will operate. This code protects your compressor from operating with less than minimum freon and oil carrier that lubricates the compressor.You can purchase a freon kit at a local parts store for about 25 bucks, but will be unable to put the freon in until you clear that code. Your vehicle probably has to be hooked up to an OBDII reader in order to clear the code. You could search on line to see if you can find a method that would allow you to clear the code with a jumper on the OBDII input connector. Otherwise you may have to have a dealer do the recharge, and they will insist that you fix the leaking problem that could run into hundreds of dollars.
