Number one: The air bladders may not need air. Number two: The fuse is blown. Number three: The compressor is 'burnt' out. Number four: Loose wire. Number five: As stated previously, if the car has been 'lifted', you may be able to fix the problem by turning off the key, opening the truck, placing the air suspension switch in the 'off' position and then after starting the car turn the switch to the 'on' position. Could be simple. If car was recently towed,jacked up or put up on a lift the switch inside the panel on left side of trunk should have been turned to "off". Hope that's it.
The Mark 8 does not have a check-valve in the air suspension system. Each air spring has a solenoid valve, which controls fill and vent of the spring. There is a fifth in the suspension compressor itself, which controls venting the system. I discovered that the seat for vent valve was corroded in my compressor, which would then leak when the system was trying to fill. This resulted in the compressor running, but the car lowering. I was able to clean the seat up for a temporary repair, but ultimately replaced the compressor.
Most commonly would be lack of freon.
My first guess would be you are low on freon.
low freon, bad pressure switch, bad compressor clutch.
Can't do it. The lubricant is mixed in with the refrigerant. Converted to air it would be running dry.
A/C compressor? A/C compressor?
there are several causes to the air pump. the first and most obvious is the air pump (compressor) itself. if you do not hear the compressor pumping air or if you do not feel the slight vibration of the compressor when you put your car into drive, then it's probably the compressor that has gone bad. if the compressor is coming on and you do not hear any air leaking, then your problem could be the height adjuster, located on the suspension bags themselves. Bronconvict: another possibility includes the compressor relay switch. This switch controlls the power to the air bag suspension compressor. This switch is known for burning out when the suspension compressor is working too hard. This can also be caused by a bad/corroded GEM module (due to notorious winshield leak). i had to replace "height sensor" on driver side . part was $200.
I'm not sure why you would want to disable this.. There is an on and off switch in the trunk on the passenger side. In the off position the air compressor will not operate.
No, a bad rear sensor to an air suspension compression would not directly make a motor not work. It can cause a battery to drain which would cause starting issues.Ê
Most likely you have a damaged - locking a/c compressor internally.............
I would like the answer to this question also. AnswerWhen you say "after turning off 1994...", I'm assuming you mean turning off the A/C. The clutch on the compressor might be stuck, or the relay that controls it may be sticking. Try pulling the fuse or unplugging the compressor connector and seeing what it does. If it still runs, you've got a bad clutch on the compressor. IF YOU PULL THE CONNECTOR AT THE COMPRESSOR, MAKE SURE THE ENGINE IS OFF BEFORE YOU DO. Don't blame me if you get hung up in the belt.
Not without raising the suspension it would reduce your turning ability and would rub the wheel well.
