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.
