A/C compressor will not kick in. What might be keeping it from engaging?
AC compressor won't kick in. System pressure is good. Relay is good.
New pressure sensor installed. Compressor still won't kick in. Jumped the
compressor from the hot side of the relay to the power for compressor and it
ran. Initial problem was the blend door was stuck in hot. Changed actuator.
Still stuck. Changed cabin HVAC controller. Blend door worked but
compressor would not kick in.
