94 civic ac diagnostic
1st. post. 1994 civic ac performance test. @ 1500rpm low side 55 to 65, high side 155 to 180. Blows cool air, not cold. this is after system evacuation (2hrs.) and recharge. Driving 55mph system is cool, not cold, come to a stop no cool air, back to 55, system cools again, but not cold. Seems like compressor is not up to par. It's all original equipment. Any input is welcome, thanks.

And yes, a bad compressor is a possibility, as is a faulty expansion valve.

Re: 94 civic ac diagnostic
i ran performance tests again, this time low side was high at 80 psi. high side low at 135 psi. outside temp 90 degrees. i lookedinto the evap. compartment, evaporator and expansion valve were cool to touch, no frost. i cleaned out the debris and closed it up. system still blows cool air, not cold. the additional symtoms on the chart were not present. the chart points to comp. and expansion valve replacement. i'd like to be more sure before i make this repair. any more insight?
