Hi, I like to know which side is a cylender #8 on 1998 mercedes benz s 420
I just picked up the vehicle at body shop having the front bumper repaired. Turning on the air conditioner, no air flow is generated. I tried to remove "auto" set on driver side but this stays activated ( at least light is on). When I try override and setting fan to high directly, nothing. Defrost/heat/air all result in same result. Fuse/resister/switch gone bad or is the blower the issue? The sensor in the front bumber the issue? Any assistance is appreciated.
We replaced the trans, & it won't shift, even manually. We replaced the tcm with a used one, but neither the old one or the used one has voltage to the solenoids. The white wire (+) has no voltage. It supplies power to the solenoids from the tcm.
DOES ANYONE KNOW WHAT A D MODEL VALVE IS?
I REPLACED THE BLOWER MOTOR AND AM NOW GETTING FORCED AIR INTO THE PASSENGER COMPARTMENT. UNFORTUNATELY THE AIR IS "WARM" NOT HOT. I'M TOLD THAT A PART THAT SITS ON TOP OF THE ENGINE BLOCK (ON THE RIGHT HAND SIDE IF YOU ARE FACING THE CAR). THE PART HAS THREE ALUMINUM CYLINDERS ABOUT 2" TALL AND 1/4" IN DIAMETER. I'M TOLD THAT THE HEAT FROM THE RADIATOR MOVES THROUGH THIS PART AND IT MAY BE CALLED A "D MODEL VALVE". I CAN NOT SEEM TO FIND A PART BY THAT NAME ANYWHERE. ANY IDEA(S)?
