If you only need the A/C to work (at least for now) on the passenger side, remove the panel from below the glovebox. It requires, I think, a 7 or 8 mm socket. Once this is down you will see a little white, plastic arm hooked to a threaded, metal shaft. Manually push the shaft and plastic arm toward the driver's side of the vehicle and cold air (if the system is, in fact working properly) will miraculously come from the passenger side.
You can take a plastic tie-wrap and secure the arm in this position as long as is desired in order to obtain the desired result, but of course, me-says go to your nearby mechanic and have him replace the programmer (it is a bit costly, but if your LeSabre is in any decent condition it is worth the investment).

Front AC cold but Rear AC very hot


Not likely, but Is Hot water flowing to heater coil in back? How hot is "very hot" Is it a refrigerant line? If a refrigirant line, Very Hot means it is hot gas from the compressor that "should be going to the condenser coil usually in front of the radiator. It's almost impossible for that Hot refrigerant gas to go to the cooling coil in the back unless you had some repairs done and they weren't certified. My guess is the radiator hot water is not being controlled properly, due to bad valve or control system components.

Heating, AC and vent problem


The actuator door that is behind the dash that closes off the heater core from shooting hot air thru the vents might be your problem. When you turn on your ac the actuator shuts the door to prevent the air from flowing thru the heater core into the cabin, this may be your problem if everything else is working properly. Let us know.

AC blowing cold trough the 2 drivers vents & hot trough passenger


sometimes this will work depending upon the severity of the problem. also the 2 vents that are not working is because somewhere in that network of ventilation duct hoses is some blockage and it is a nightmare to fix this because you have to remove the entire dash and face plates etc.........

Passenger side a/c blowing hot air, driver side is cold.


There's a rod assembly that opens and closes the vents in the car for the automatic climate control. It's supposed to open all vents to the AC feed when in AC mode. BUT, if it slips loose, the default status is to feed heat through (you can open a window in the summer, but you don't want AC blowing in your face and on your windshield in the winter). In my case, the driver's side was working right, pumping cold air, but the passenger side was actually dumping hot air into the car. Friend who fixed it for me told me he just had to drop the glove box etc. on the passenger side to get to the rod and slipped it back into place. I'm not agile enough, but if you are, you can probably crawl around under there and figure it out - or get a friendly mechanically inclined young friend to do it for you. Probably in the mechanic's manual for the Caddy (I don't have one).

Think this will fix it for you - did for me.
