cohophysh Posted July 9, 2012 Share Posted July 9, 2012 Does anyone have a good link to troubleshooting the A/C in a 90 legacy. The compressor would run but all that came out was hot air. Link to comment Share on other sites More sharing options...
bstone Posted July 9, 2012 Share Posted July 9, 2012 Was the AC clutch engaging? Is the system charged? Link to comment Share on other sites More sharing options...

Rooster2 Posted July 10, 2012 Share Posted July 10, 2012 yes on both accounts Is the compressor clutch cycling on and off about every 3 to 5 seconds? Link to comment Share on other sites More sharing options...
capn_r Posted July 10, 2012 Share Posted July 10, 2012 What are gauge pressures when it is running? I'm guessing a txv issue. Link to comment Share on other sites More sharing options...

capn_r Posted July 10, 2012 Share Posted July 10, 2012 Thermostatic expansion valve. It's the metering device for the refrigerant at the inlet of the evaporator. If the refrigerant charge is close to what it should be and cooling isn't happening it may be not metering properly. System pressures would help isolate what issues exist causing the lack of cooling.
