Look under the hood of the car. In the center near the latch there will be a sticker that tells you which it is. My 1992 dynasty uses 34oz of R-12.

Where is the air conditioner blower fan relay on 1996 Jeep Grand Cherokee located?


The blower fan relay is located in the fuse box on the driver's side fender-well. A Jeep Cherokee uses an electric fan as an auxiliary fan for engine cooling and for cooling the air conditioning condenser when the air conditioning is in operation. A radiator temperature-sensing switch that activates the fan relay at 198 degrees F turns the fan on and controls its operation. The temperature drops when the vehicle is in motion and the switch turns the fan off. When the air conditioning system is in operation, the air conditioning relay supplies power to the fan relay via a fan diode downstream from the ignition switch. This diode activates the fan relay and keeps the fan operating as long as the air conditioning is on. Thanks. you can rate this solution and show your appreciation.

I have a 1992 mercedes 200 E WDB 021 Saloon, it has 8 button air condition and I dont know how to use it. Control wheel on blue position but When I push the button (leftmost)which has a glass figure on it,...


The pulley on the air condition has to turn it has a belt on it. The Compressor engages to pre cool the evaporator. Most likely you have a blend door pod leak or leak in the hose or the sampler valve is bad. I would replace the sampling valve behind the glove box/air bag. As that reads the cabin temp and if it thinks the car is cold the heat will stay on because everything is automatic. All vents will blow cold when it thinks its hot and in addition to floor and corner dash center vents will blow cold when it works. If the direction of air is correct then the A/C system may have a leak or need a charge of freon.

Air conditioning is bad


Early use of the new type freon - kills those old seals quickly.
You may have a cracked O ring seal in the high pressure side of your air conditioning system. Have it checked with a leak detector... that should tell which seal is leaking.
