QuestionQUESTION: A follow up question to the 1972 Monte Carlo, blows cold air, fan speed changes but no volume change when max a/c selected. I have a new fan switch and have eliminated, everything down to the resistor, which you mentioned in your first response. I have not been able to find a replacement. My question is, can the resistor be bypassed or do you know of a replacement resistor.
ANSWER: Ed,
I apologize for the delay, we had an electrical storm and the power has been out for a period of time. I also apologize because I was unable to research which question exactly this pertained to. Do you remember when it was asked, I receive quite a few of them.
Anyways,
As for the resistor, no it cannot be bypassed or you will only have high speed on your fan. You can however probably repair the old one if you know a little about soldering. On a car made before they made them non-user friendly most of the electrical components can be fixed by the owners.
First, check the resistors individually to determine which one needs replaced. You can find the replacement resistor somewhere like radio shack and then it is just a matterof soldering back into place.
As for a generic replacement, I don't know of any off of the top of my head. But if you look at a place like yearone.com or classic industries, they sell many oem or nos parts for classic vehicles. I know this because I do alot of business with them for my 73 Nova.
Thank you for the question, I hope I was of some assistance. If so, please remember to rate this answer. If I can do anything further during this process or in the future, do not hesitate to ask. Thank you again and good luck in everything.

QUESTION: Thanks for the help on the resistor. I ordered resistors for a chevelle and full size chevy. They have a different connector pattern. As for repairing mine, do I read resistance across the individual resistors until one reads infinity.
AnswerEd,
First read the resistance across the entire block, and then each individually. The one that reads OL or infinity on the multimeter is the one at fault.
