In your statement below
I do find it odd that something realted to AC (with is not necesaary) would keep fan from coming on and risk overheating. Feels like overheating prevention should take precendence over AC - maybe this suggestes thatere is something else going on. This is basically what i am asking in this forum But with different condition. I have overcharged my system with R134a and the discharge line goes above 370psi and activated the Hi Pressure switch. I find it odd for the pressure switch to switch OFF my Condenser/Rad fan when engine temp is very high (going above 98C/208F). It risks the engine to overheat when temp continues to go up with condenser/rad FAN OFF. I hope somebody here can share a schematic of Gen3 or Gen2 for the cooling wiring diagram showing the relationship to the pressure switch and condenser/rad fan |
