Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Are you working with electronic air (buttons) or manuel air (knobs) ?If you place your hand on the accumulator on the passenger side of the firewall is it getting nice and cold with the AC running?
The accumulator is the receiver/dryer (large black cylinder) located on the passenger side on the fire wall. Can you check it with the AC running and see if its getting cold ?
Okay how about the larger of the two hoses coming off the compressor, is it getting cold and have you installed a set of pressure gauges and read the system pressure?
Can you run the self test on the system and let see if there are any fault codes setting, see the steps to do this in the link below.
So did you get a code?
Well Im thinking you may have an expansion valve issue here if n the rear is cooling but with out being there to read your pressures and do some hands on testing I can not say for sure. I can open the post back up for you as I do not think I can fix this over the internet .
Unfortunately they my be your best bet. Good luck to you as well.
