Unless someone has modified your car, the front system is the same as a single system car. When the engine iswarm and you have the selector level on hi does the compressor run?
If not, does it run when you reach up under the master switch and press upwards,?
Is the connection at the master switch good?
Is the on ection at the blower relay good?
Finally before you go much further, does the motor run when you take a jumper wire from the +post of the battery to the blower motor terminal itself?
