'63 Valiant V200 wagon - location of heater blower resistor

[shortmort37]

Off of my heater blower switch connector, there's another two-wire connector that's dangling:

The wiring diagram indicates that this connects to a "heater blower resistor" somewhere under the dash (as shown to the right of the firewall bulkhead connector):

But there's no receiving connector in sight. Where should I expect to find this resistor - and if it's not there, where can I find a replacement? I haven't yet found the P/N in my parts book.

adTHANKSvance,
Dan

Found the P/N. Now, where does it go? And where can I get one?

Ah! Found it, in the service manual. It appears to be on the firewall near the heater assembly. Now to crawl under the dash and see if it's still there.

On my 65 the resistor was actually on top of the heater box

May have to take the radio out to access it.

In the heater box, just where I told you on Facebook. That's where they all are. Whether the wiring goes straight from the blower or the switch. Glad you found it.

Yeah, that "in the heater box" threw me - but the resistor was "on" the heater box, and the connectors are now mated. And the radio was already out to replace the defroster grates. Thanks to all for your suggestions and help.

Thanks for the update. Some posters never let us know how things turned out. Or express their appreciation for our advice.

Buddy I have the exact reverse of your problem. The harness with the black and brown wires that connects to the resistor is there but I don’t know where to connect the wires to!

It’s a 65 valiant

Mine are both brown to the resistor - they go to the fan switch connector. I believe the switch puts the resistor in series with the motor for low speed, and shunts it for high speed.

Wow. Your heater switch is different than mine , but you’ve answered my question and confirmed my suspicion. The wire goes to the switch. I’m not good with reading schematics. I jimmy rigged a power source off of the fuse box and put in an inline switch (a household light switch) to the resistor (which powers the fan)until I can remove the factory heater switch and do it right. I don’t want to lose out on driving time because we’re in the prime of our summer in Delaware , defrost is very necessary here because we’re known for dense fog here on the shore. Thank you again and especially for such a prompt response!

 

[shortmort37]

If I'm correct, the resistor is needed to reduce the speed of the motor at the low setting. If defrost is a concern, you might want to wire up your switch directly to the motor - "high speed" - and bypass the resistor ("low speed"). Until you get this sorted, anyway.
