2000 Lincoln LS Repair Question
Mileage: 144,560 miles.
What to look for when the air compressor won't come on? the fan motor is running but air compressor won't operate.
Answer
You need to start with pressure gauges. If you see over 80PSI static pressure, then you have an electrical issue and you will have to track it down with a wiring diagram.
Have attempted to install freon. It doesn't allow it to come up to 80 psi without the compressor cyclying.
That means you have an electrical issue that needs to be troubleshooted.
Lincoln is VERY hard to charge to R134a spec on the decal with a charging station, take it to a garage with an a/c station, this might solve your problem. Had to do it with my own 03 TC...
The other thing is with 145,000 miles, the compressor itself could be the issue.
Refrigerant is not the reason the compressor is not coming on. It has 80 PSI static and that is plenty to energize the compressor.
Try disconnecting the battery for a minute. Some will set a code for low refrigerant and then lock out the system until the code is cleared and then it could be charged if that were the case.
I though he said he could not get 80 psi into it... if the compressor runs but cycles due to low charge, use a charging station.
The other point with r134a is at least on FLM cars they are almost if not impossible to charge accurately with a gauge set.
What does the gauge read with the compressor not running?
