MY suburban AC wont put out cold air. I check the presure with a gauge and it at 100 psi which is too high. I recently had to install a new Ac control unit from my dash board bcuz the other one wouldnt work. I am not sure what to do next.

Clarification Request

obviously the compressor is running? i usually see the low around 25-30 and the high at 150 maybe low on freon but it all depends on ampient temp and humidity
