Have you checked the AC charge? Compressors will not kick in if the system is empty.

 

it seems empty actually, but how it will take the Freon if its not running, we tried and didn't work ?
Suggested ways ?

However, keep Im mind that we checked the power and its not getting to the compressor, according to some other suggestions I probably need to check the PCM connectors ?
Unless someone can exactly tell me which relay or fuse is for my A/C compressor, which I cant seem to figure out.

Thanks

 

The A/C clutch relay is located in the IPM, aka the front power distribution center, under the hood, left/front of the engine compartment.

After opening/removing the lid, and while standing in front of the car facing the rear, the A/C compressor clutch relay will be seen at the left rear corner of the IPM, second relay to the right from the corner.

 

Thanks guys for all the info!
I will definitely get the leak fixed, once i figure out the main problem with the compressor, or at least force engaging it to make sure I have no power issue beyond the relay.
Hopefully not PCM problem though.

 

I think you will find that once the leak is fixed and you start to add the R134 refrigerant, the pressure of the new R134 will close the low pressure switch and the compressor will kick in to take in the additional R134 for the system to run normal.

 

...and all of a sudden my a/c compressor stopped working.

If your AC works one day then not the next, there's a good bet that you caught a rock in the condenser. Check for fresh oil stains looking into the condenser through the grille and lower air dam areas. Additionally, check all the hoses, fittings and pipes for signs of leaks. Oil will be present at a leak.

I'm not sure if the 05 has a 2 wire low pressure switch, or a 3 wire pressure transducer, but if it's the 2 wire type, you can unplug it, and jumper the connection with the AC tuned on and blower fan on any speed. On my 08, the low pressure switch is in a line near the service fittings, by the master cylinder. If the circuit is okay, the clutch should engage. If you locate the relay, you can jumper 30 and 87 to bypass the control side and check the clutch coil circuitry independently.
Happy troubleshooting and
Good luck!

 

And how do I find 30 and 87 to bypass it
