No the rear AC is not blowing cold either. Same as front. But it did work like front until AC compressor stopped engaging last Saturday.

Yes I replaced the compressor, dryer and o tube when I installed new compressor. I vac'd it down and did refill.

When I hook up test light to battery positive and touch compressor wire harness from back of compressor - the AC clutch will engage and I get cold air.

AC Relay is brand new. All fuses good.

Can a bad condenser cause this? I only ask this question because I go back to my original problem that was it not blowing cold at stop lights - idle.
Can the condenser completely fail and cause compressor not to engage?

I can't shoot dye into system to look for leak because AC won't engage.

Should I VAC it all the way down, and start from scratch? I guess I could take everything apart and look at the o tube.

Just not sure what the smartest approach would be money wise.

I do know the condenser has got some miles on it for sure. I would go ahead and replace the condenser if I knew a failed unit could cause the AC compressor to not come on.

The round connector on the back of the compressor that connects to the ac cycle switch

The round pressure switch on the back of the compressor. Put a test light to that and battery positive compressor clutch engages

95 PSI on low side - 2:30 o clock on gauges
100 PSI on high side - 8:30 o clock on gauges

The AC was turned on for these readings.
