I'm assuming this is equipped with the 4.1 liter engine, and it's FWD. Since it runs off the serpentine belt, not easily. If anyone makes a bypass pulley for it, that would work, but I've never seen one for these cars. All it would be is a bracket that bolts in place of the AC compressor and has a pulley on it for the belt to go over it. It would just be like having an extra idler pulley. If you have the skills and equipment, you could make one. If you're accustomed to fabricating (ie - a machinist, tool and die maker, or custom car builder) you could make it yourself fairly easily, but I wouldn't recommend this for amateurs.

92 cad deville first pass elec window stopped up-down 2 wks later right rear window stopped 4 wks later left rear window stopped driver side still works?

Sounds like your master drivers side window switch is on its way out. If you can find a working used one you can save some money. It will interchange with Cadillac Deville, Fleetwood FWD 4 doors from 85-93. Also a lot of the 4 door Olds 98 (85-90) and Olds 88 (86-91) have the IDENTICAL switch.


You just bought a 86 300zx non turbo and gave it a basic tune up and now it sounds and feels like its sputtering and not wanting to idle you know its not missing it stops at about 2500rpms whats wrong?

It the air bypass unit. be sure there is no leak and the electric connector is attached. To test I have taken it off and temporarily installed a rubber hose. What happens is when you start car the air bypass is open and increases engine idle. Inside the air bypass is a heater that shuts off the air bypass once the engine is up to temp. The air bypass is on right side of engine. It is bolted to engine with two bolts. Air passes out engine through the air bypass and out a big hose connected to air bypass.
