It could be a couple of things:

  • First check the fuse, it may have just been blown.
  • If the fuse is fine then you could be low on refrigerant or have a bad pressure switch. If you're low on refrigerant, the pressure switch will not allow the compressor to turn on.
You can buy an inexpensive pressure gauge at an auto parts store to check it. Unless you're real familiar with a/c systems, I wouldn't go much further than that, just take it to a shop.

Good Luck!

What could be the problem


Pull the pump out and see if just running 12 volts across it gets it to work. If that happens then it is not the pump at all but more likely fuse board or even the body computer.

Electrical fans wont kick on, car will run hot if they dont kick in..Tried changing fuses still wont come on..


The fans have a seperate temperature sensor either in the radiator or the block. Follow the fan wires to locate this sensor and unplug the sensor and with the key on touch the wires together. If the sending unit is bad the fans will come on. If the sending unit works the fan motor is bad.

Lost keys have hot wired it wont start but does turn over wants to go what do i do


Take your title to the dealer, they should be able to make you a key, also do you hot wire hot to ACC/ON hit Start, then release back to on when it turns over? It may not run if you have anti-theft.

Horn wont work


Unplug the wire to the horn and make sure you have the horn grounded really good. Take a hot wire and run it from the battery to the horn. touch the hot wire to the end of the horn and see if it works. If it does not work then you need to replace the horn. If the horn works then take a test light and hook it up to the horn wire and have someone push the horn down. you should have a hot wire. If you don't them check the horn fuse. Let me know if this works.
