'65 blower resistor location - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi Guys,

Helping my son get his old truck up to snuff. Just ordered a new heater wiring harness and resistor. It's a Deluxe model. Bench tested the motor it's fine. Under the dash is a nightmare. Correct me if I'm wrong but I believe the resistor mounts to an opening in the air box. Here in lies my confusion. There appears to be a rectangular patch over what I assume was an opening located pretty far up the box on the passenger side. As well there is another opening just to the left of the passenger's floor vent. It's a larger rectangle. Anyone have a picture to share of the resistor mounted as well as the ducts for the driver's floor side and defroster ?

A second point of confusion is where the 'temperature cable' at the control is mounted. The control panel is minus the control levers at the present time so I'm in the guessing stage. The cables for the defroster and air are obvious because their labeled. The center lever is defined as fan........ obviously somehow controls the switch. Does it as well control the temperature cable?? Any ifo would be deeply appreciated.

Here is the answer - http://67-72chevytrucks.com/vboard/s...88&postcount=6
LMC has replacements.
Some more info with a manual pic - http://67-72chevytrucks.com/vboard/s...d.php?t=579293

RockinRod,

Thanks. So I think what you showed me is that the resistor is installed to the interior of the box at the interior side of the firewall. At 71 years old I'm not new to backyard mechanics. I'll happily take it apart to see what you showed me. Next guestion therefore is where do the wiring harness wires route?
