A/c no longer blowing cold in 96 tahoe


Tried to add freon but the gauge on the can says I’m at 40-50. while recharging , the compressor keeps clicking on and off.

New compressor switch can you help?


[b]The problem is you’re not monitoring the high side pressure of the system as you’re attempting to recharge the system. The high side pressure tells a lot on how well the system is working.

You need to have a manifold gauge set connected so both the low and high side pressures can be monitored when recharging. Otherwise it’s just a guessing game.
