Heater motor

[simplyconnected]

Provided your heater motor is two-wire:
Junk yards throw them out, daily. Every car in every brand uses them. They have the kind that bolts on and enters into the heater duct with three electrical stabs:
1. to - Motor
2. from switch - MED speed
3. from switch - LO speed

If your switch only has HI and LO, just hook up two stabs (1&3).

Remember, HI speed is a direct 12-volts from the switch (HI).

A clarification of my previous post above: All A/C units I have parted out had a large diameter fan motor but only TWO wires, an orange and a ground. The non A/C cars of course have the red, orange and black (ground) wires and the fan motor diameter is about 3/4 the size of the A/C motor. The A/C setup still has the red and orange wires in the harness but they come together in the 4 way connector Howard speaks of. The two wires exit to the one orange wire on the motor. The fan speeds are regulated by the resistor in the fan chamber on the A/C cars.
I have seen the smaller motors with three wires used on A/C cars. They fit, the shaft diameter is the same as are the mounting provisions.
I'm not sure what fan speeds are available if one wire runs thru the resistor when using the 3 wire motor. Anyone?

@ Carl: I like this answer, as it means I´m OK again

I´m 100% sure Howard and simplyconnected is right, but I got a bit lost to be honest...

Sorry Anders, my last post was an answer to Dakotaboy's question about where to find a resistor.

[Howard Prout]

I think Carl has the best explanation. My car didn't have AC originally - I added it. That was too many years ago to remember the details. My guess is that I didn't change the blower motor - just used the original, which is why I have a three wire motor in an AC car.

Dave,

The wife stole the last Ben Franklin outa my wallet this morning.

Can you wait until tax-return time? (jeez I hope I get a refund)

What? Your wife took my money??
Well if she's cute, tell her I said, "It's from me." And, she can keep it. - Dave

Oh, wait...

She IS VERRRRRY cute. That did it, the hundred bucks is hers.
