My g100 1991 charade the AC doesn't work so I would like to disconnect it. I have no interest in repairing or replacing unit, I would just like to disconnect for potentially better fuel economy and less engine wear. Thank you for responding. I apologise I should state that the ac control unit is not responding and have issues with the compressor. When it's turned on, the AC causes the car to shake rather violently. Hence why I would like to disconnect or remove if engine performance improves.
Fuel economy wont change if you dont run ac but you can go to auto parts store and get a belt for a car without AC
Simply unplug the electronic wire that goes to the compressor the compressor will no longer work I agree with both answers above you can take the compressor off or just simply remove the compressor belt no need to if you just simply unplug it
If your ac doesn’t work it won’t decrease your fuel economy unless you are running the ac so without properly recovering the r134a that is in the system then don’t worry about removing it
Remove compressor drive belt I guess, removes main mechanical burden ...if you want to remove compressor itself, or even condensor, to save the weight of car carrying that now redundant component around, you can do that too..bear in mind before loosening off any hoses or steel gas lines of the system that it will contain a/c coolant gas still under some pressure. Compressor is the main weight and mechanical burden on engine, although when system is switched off the compressor pulley load drive effort is low, anyway.
if car has one "serpentine" belt driving everything, rather than a separate AC drive belt, then, it is possible that removing the compressor will necessitate fitting a new shorter engine belt compatible with no AC.Depends of car's belt arrangement.
Thank you for your reply. It's a serpentine belt drive. On the weight reduction though how much would it be likely to free up.?
Chances are on a small car like that,with more modern lighter components, the a/c compressor, condensor and hoses may not amount to much more than 10kgs..if it is, it would be highly unlikely to exceed 20kgs..
I don't know what the legalities of opening the system and loosing the gas off yourself is (and if it was my car, it probably would not factor in much with me,as opposed old R12 gas , R134 gas is not a CFC anyway so far as I know) , but, from a safety pov, wear good eye protection on the off-chance that suddenly escaping refrigerant could fluke a squirt-hit on your eyes.

hi there, your either low on freon or the relay is kicking out sometimes, have the relay checked
SOURCE: 91 deville fuel gauge flashes "E"
It seems that you are low on fuel based on you saying 70 miles in the range gauge. If this problem does not happen with 3 gallons of fuel or more then it is normal. The range is calculated on your average MPG and gallons of fuel in the tank. When the car gets to around 2 gallons it does not chance miscalculating your miles to empty and leave you on the side of the road. At this point he tank will read "E" to let you know it is time to fuel up. The flashing "E" is simply cadillac's way to get your attention that you are in fact low on fuel and need to take action. Hope this helps.

You can replace the ac with a pulley kit $35 but you still have to remove the ac you can drive the car with a bad ac unless the bearing is bad and it locked up like mine then you can cut the belt and drive it but you will have no power steering and your battery won't charge

You can save a LOT of money by fixing it yourself.
All that is wrong with the knob are broken wires from the knob's PC board to the main PC board on the AC control.
All you have to do is remove the AC main control, take it apart, and resolder the broken wires from the PC board with the knob on it, to the main AC pc board. There are 3 wires, any number could be broken.
If you take it apart and solder the broken wires, this WILL fix your issue. Just make sure you put the wires back exactly where they go.
A FIXYA rating (4 blue diamonds) would be most appreciated for my assistance.
SOURCE: How to replace bulbs for ac/ heater control unit
1. Remove the dash around radio (just clips)
2. Remove 2 screws pointing up . (You do not need to remove screws which are parallel to the floor)
3. Remove screw pointing up on the bottom of the dashboard on left side of the driver (near left leg).
4. Remove 2 screws pointing up in the instrument cluster area.
5. Put car in 1st gear and gently remove black plastic surrounding instruments (it will have ait vents, so slide it carefully out not to damage foam insulation on air ducts; start on the bottom hear steering column) ; unplug connectors to clock and emergency flashers.
6. Remove 2 screws, now exposed, near instrument area, holding dashboard. (that was what I spent most time on, I didn't know about this screws.
7. Now gently remove (or move up) dashboard (around instrument cluster and heating controls.) Start next to ignition (careful not to damage the bulb next to the ignition.
Since you only need to get to the heating controls block, I only move up the dashboard next to it.
8. Remove 2 screws that hold the heating control and slide heating control out . This step is unnecessary If you totally removed the dashboard.
9. Pull out lever controls for fan speed, zone and temp
10. Use the screwdriver (flat) to pry 2 plastic tabs on top and on the bottom of heating control so black cover can be remover.
11. You did it! two bulbs are going to be under the cover.
