as I understand it There appears to be a air conditioner module behind the radio in the center console which is actually tied in with two other computers onboard and the module is not sending information to start the compressor. Cost as I understand is about , are you ready? Eleven hundred ( $ 1,100.00 ) dollars. Plus labor. At least that is true for a 2003 SL 500. from Mercedes Tech.
Yes, with both freon and oil for it to operate correctly and engage unless someone has bypassed the pressure switches or relays..........
You will have to figure out why: This the 90% of the time failur: Is there Freon in the system, if there is not a minimum pressure, usually 17 PSI, the compressor will not run. Is the compressor and clutch capable of working? Is the fuse in good shape.
It can damage the compressor.
The compressor.
This could be because you have a leak in you A/C system causing a loss of freon. When there is not enough freon in your system the A/C compressor will not engage, it will harm the compressor.
The air conditioning system is behind the dash like all other cars. The compressor, however is mounted on the engine, in the rear of the car, with refrigerant lines running up to the evaporator/condensor up front.
You should not put any oil in a Ford air conditioning compressor. The air conditioning compressor runs on Freon. The system should take about one pound of Freon.
that depends on what is wrong have you checked the compressor?
If the compressor will not come on at all, it is not because the system needs charging. Check for a blown fuse, disconnected wire at the compressor, or a defective compressor clutch.
You will need to remove all of the Freon from your air conditioning system. Remove the air conditioning hoses. Remove the compressor belt. Remove the compressor retaining bolts. Reverse the process to install the new air conditioner compressor.
You don't need to engage the compressor clutch to recharge the system. In fact, you shouldn't engage it without refrigerant and oil in it, because the refrigerant carries the compressor oil in order to lubricate the compressor. But, to answer your question, you disconnect the low pressure switch, and run a jumper wire between the two female ends of the connector.
On the line right at the compressor.
