You should be able to check out those parts-yard resistors with your multimeter set at ohms scale, see " target="_blank"


No multimeter? Then tough to troubleshoot stuff like this, electric water heater, clothes drier, etc.

Hopefully you flushed and blew out the lines, condenser and evaporator when you did this.

Mazda I got it from was aftermarket system already on 134, and not a retrofit. Pretty dang cool. I just blew everything out

Sorry, you should have mentioned earlier that it was aftermarket system. So the wiring and wiring diagram posted above may be different !!!

No. It's all the same. Everything plugs right in just like dealer installed air. The truck I got this system from must of had this installed after '94. I had to change condenser, all hoses and the bracket. But other than that it all plugged right in.

OK, check out your blower resistors, see if the values are as described in the Tech Help link above.

Hopefully, yours was a dealer-type kit as even my 1988 was dealer-installed when it was sold new (a Wynn unit from Texas, have the sticker). I will say that these kits work nice on the B-trucks.
