1972 Chrysler Imperial Le Baron workshop manual

Has anyone got a workshop manual for the above or can email a copy of the A/C wiring diagram as I can`t get the Fan to work to demist the front screen.

If the fan runs for the heater and a/c then you have a vacuum problem. If the fan doesn't work at all then it's probably the blower motor resistor. Here is a place to find the wiring diagram you need. http://www.mymopar.com/index.php?pid=24

Thankyou, that is a great help, now I can trace out the wiring. When you say there may be a vacume problem will that be in the control box mounted near the R/H fender?

When you move the controls from heat to a/c does the air change from blowing out of the heater vents under the dash to the a/c vents in the front of the dash?

Does your Imperial have autotemp II? Or the regular setup?
