Hi,
They have a condenser relay. I never heard of one. The condenser is the unit that sits in front of the radiator and actually looks like an additional radiator. There isn't anything electrical in it that would use a relay. The only thing I can think of is they are referring to a condenser fan relay, but this vehicle doesn't have one.
So, I need to know what is happening. I can tell you that the A/C compressor is controlled by a circuit in the totally integrated power module (TIPM). Because of the large number of wires going into each of the TIMP connectors, the pins are very small and known to corrode or break causing a disruption in power.
I attached a pic below so you can see how the A/C compressor is actuated.
Let me know exactly what is happening and what has been done so far.
Take care,
Joe
