AC: Can I jump the dash ac sensor wires without harming anything?
I have the dash top off and I want to operate the Climate Control system, but it won't engage the fan properly because the sensor is missing. If I jump the wires to regain functionality will that burn anything out?
Thanks
Norm

Hi
jumping the in-car temp sensor reduces the total resistance of sensor circuit, so Confort control sees that it is very hot inside and will put full AC on. In-car sensor has the biggest impact to total resistance. (Source: CadillacTim`s AC Guide)
Electronics component shop might be able to find a correct resistor for you if you show them the table below.

Thank you.
My purpose is to run the system with the dash top off. It seems the fan will only go on low with the top removed. I am tracking down an air path issue.
When the top is on and everything is connected and HI Auto is selected, the fan sounds loud but the actual amount of air coming out of the ac ducts is not in proportion to the speed of the fan. Somewhere there is either a blockage or an improper diversion/leakage of air. I am also going to try to examine the evaporator to determine of it is blocked by leaves and debris.
Much appreciation for your input.

Loud air moving sound within carb with cleaner removed

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
Vintage Air AC

Hey everyone, has anybody done a Vintage Air AC/Heat setup in their car? I want to bypass the old vacuum setup and go with a Vintage Air Gen 2 model. Before I get started, does anyone have any experience with this? (Which model to go with, do’s and dont’s, etc.) It looks pretty involved. Any and all info/pics would be greatly appreciated. Thanks!
