Question about 1994 GMC Suburban
Ac system reading way to much pressur and it does not blow cold air in my 1994 gmc suburban
Too much pressure in the ac system is just as bad as not enough pressure... to much pressure can actually stop the ac compressor clutch to not be able to disengage therefore ending up burning out the compressor... start off with checking if the compressor is engaging then if it is bleed off some of the pressure until its in the proper range... if that still doesn't solve the issue you may have some moisture in the system and will therefore need to have the whole system vacuumed out and replace the drier then recharge the system.
