I have a malibu 2016 LT 1.5,

When I turn my ac on the compressor engages, but my fan does not turn on, sometimes the fan does turn on and the ac works fine. The does not over heats at all.
I was thinking maybe the ac pressure switch signal wire has a bad connection, it looks like the previous owner replace the pressure switch connector.

What do you guys think? What should I check next.

Pressure switch would not affect blower, only the compressor.
Blower wiring connections, speed resistor if manual controls, need to be checked for bad connections. Giving the blower motor a smack when it's not starting up is a quick check of it as the motor brushes in it wear and make erratic contact and operation.
I was talking about cooling fan not cooming on when I turn on my ac, the weird part is that the compressor engages with out the cooling fan comming on,

Can any one tell what color is the signal wire. I been researching online no luck.

Another questions does any one know if the malibu 2016 lt 1.5 has a fan resistor?
