I'm pretty certain that the resistor is the same on the 70 as the 69. Is up
a ways under the dash at about center, If it is bad, the coils will probably be
burned & melted. Another possible culprit is a vacuum leak.

Subject: IML: Auto Climate Control
I have a 1970 Imperial with Automatic Climate Control. Here is the problem. The heater motor
does not respond properly. If I activate the defrost, it appears to work. When
I switch to auto heat / cold the heater motor will run at high speed. The AC
works for several minutes and then quits. If I go back to defrost, wait for
the motor to start again, I can than go back to AC for a short time. If I
jumper the motor, all functions appear to be working. A test light indicates
that the motor in not getting any power. The manual states the resister block
might be bad. I cannot find this part. Any ideas? If I find it, how do I test
it.
