Are you comfortable with electrical troubleshooting & repair?  Thats the place to start. Working with the refrigerant system means buying some expensive equipment.  More practical to fix (or rule out) electrical problems then take it to a shop. How do you want to do this?  Theres a few people on here that are much better than me with the refrigerant side of things. _____________________________ '03 Accord & '07 Civic '01 Saab 9³ & '05 9²x (in reply to maro) Post #: 2

How do I test the clutch? and I''m not expert at electric, but I can give it a shot (shock)! < Message edited by maro -- 7/24/2008 1:18:29 PM > _____________________________ 1996 Accord Ex Coupe Eucaliptus Green w/ pealing clear coat. eerrrrrr. 152,000 AEM SRI Exedy Clutch NGK irridiums (replacing with the regular NGKs soon) Honda MTF (in reply to falkore24) Post #: 5

RE: ac diagnoses step by step - 7/24/2008 3:05:32 PM    JimBlake   Posts: 2920 Joined: 5/31/2006 Status: offline Other possibilities... Refrigerant leaked out = pressure switch prevents the compressor from switching on.  In that case you need to find & fix the leak. Electrical problem = lots of possible places.  Bad relay, bad switch, loose wiring, etc, etc... _____________________________ '03 Accord & '07 Civic '01 Saab 9³ & '05 9²x (in reply to falkore24) Post #: 9

RE: ac diagnoses step by step - 7/30/2008 7:48:07 AM    deserthonda Posts: 3536 Joined: 12/3/2005 Status: offline try an easy test, find the pressure switch  located rt side frt of car by the rec drier , unplug the connector, jump the 2 wires together  ( blue/yellow and red/white ) if fans and compressor engage  most likely system is out or very low on freon ,,,,, if you have a set of gauges you can hook them up and chk the pressures try this first and let us know _____________________________ No Year No Model in Your signature No Help from me Take a look in the DIY section before asking for help Always Diagnose First,,, Before Replacing Parts (in reply to maro) Post #: 15
