I read the thread on the A/C charge and appreciate you RANGER! I am doing maintenance on the water pump, and while checking it out after install, I realized that the coolant level was low and it disabled the compressor. After flushing the system and resetting the code, I put in about 18 OZ of 134a and still the compressor won't come on. What am I doing wrong? It worked perfectly before. Should I come accross the system to the fuse link to "hot wire" the compressor temporarily so it will accept the 134a?

Re: A/C recharge
When you say coolant, I assume you mean refrigerant.
If the compressor was disabled, you have to clear the codes BEFORE adding refrigerant. You must have everything hooked up and ready to go, THEN turn the A/C on to recarhge or it will detect low freon and disable the compressor again.
