the problem with no lights and power to the ac and heater control is the ground.remove the plug and on the plug is numbers find number 8 and peel back the insuation and run a wire from there to a KNOWN ground and it will work like new.the wire is BLACK there is 2 black wires it is not the one next to the red that is hot all the time.
Had the same thing happen to my truck, the blen door actuator is under the console on passenger side, but the heater core is going to be clogged if you dont have any heat coming through, but a/c works..
You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator
YOU NEED TO CHECK YOUR FUSES! EVEN IF IT DOESN'T LOOK BURNT RE-PLACE IT ANYWAY! IF THAT DOESNT SOLVE IT YOUR GOING TO NEED TO CHECK THE BLOWER MOTOR UNDER THE HOOD TO THE PASS SIDE OF THE FIREWALL- MAKE SURE IT IS PROPERLY GROUNDED & pluged IN.. IF ALL ELSE FAIL'S= RE-PLACE BLOWER MOTOR...
I had the same problem that I just fix by flushing the heater core out with a hose.
take the two hoses off the fire wall and put the water to it and let flush. my heater is putting out 150 dg. F of hot air. I'm so excited! i will stay warm now.
