Another thing is that aux fans are on high setting (bypassing pre-resistor) when the compressor cuts out. Even when I have jumped the switch for fans, it runs on low setting, then compressor cuts out and fans go on high. So it seems CCU is reading high temperature out of sudden and decides to cut out the AC and cool down the system?
I took off the connector from temperature sensor and nothing happened. Maybe it is bad, giving incorrect signal? Engine temp about 80C, ambient 110F.
