The AC blows warm air, replaced relay switch, replaced low pressure switch, checked compressor engagement, checked Freon levels, when compressor placed under load, engine vibrated and tried to stall, high pressure discharge Freon when clutch engaged under 1 minute. Engine Temperature in normal range when driving and idle. Lines did not get cold under hood. However, cold air was noticed when jumped relay switch to engage the compressor. Also noticed that the dashboard cluster is very dim at the brightest settings and radio lights are dim or not displayed sometimes. I think the problem is within the electrical system more than the compressor/condenser. Any help in this matter will be of help.
