Just searched the facques and did not find it. I have a 91 coupe and had the air converted over to 134 ,air guy jumped the compressor off battery and air worked great,he said i need a new switch. First thing i did was change out the logicon with a 86gxl parts car logicon , it lights up when switch is engaged ,but no compressor . took it out because blower function did not work. then i put in an 89 logicon from another parts car and had all functions except ac (no light too). question is there any other switches i am missing other than the pressure switch by the dryer? or is my problem the logicon.? Stupid haynes manual gives nothing on ac problems.I am old and need my air, so all you rip it out guys pass on by....Great list ,thanks for all the help in the past !

try the body electrical section of the fsm. you should be able to find that at http://www.iluvmyrx7.com
that should give you procedures for testing the logicon

Thanks for the link Shane, working on it .... fuses, pressure switch good, changed out the A/C relay still no luck. late now will check magnetic clutch cont. tomorrow and do dianostics on the ligicon . bet its the logicon....red light did come on for a second on ac button when pushed but did not stay on.

[quote name='majeskyb' date='May 14 2005, 06:25 PM']Mine is the same way. So I ran a switch from ground to the clutch wire, and flip it whenever I use the ac. If you're going to do that, make sure you but a fuse in there

did the test on the . main ac relay and had power to all except magnetic clutch think that was the B/W wire . also unpluged magnetic clutch wire and tested for current with ac on and blower on ,no current. manual says check harness .hate to hot wire it even with a fuse. could not test logicon from back side ,no room for access with it plugged in. Any other ideas?
