Why do you have no AC in 1995 buick riviera you have new ac control box and passenger side AC works?
Having gone through this same problem, No Help From Two different dealer ships, I was able to identify the problem and correct it quite easily. It appears the system, climate control, must have sufficient coolant to operate. I initially added a can of coolant and noticed no change, same as described. Being disappointed and afraid to add more for fear of over pressurizing the system, I suffered through a month of extreme heat here in the Southeast U.S.A. Finally enough was enough and I purchased another can of coolant and charged the system again. The system seem to stsrt working better but was not quite there. Having spoken with a friend who has good genral knowledge of home AC systems I tried somthing he recommended. I slowly bleed pressure off the high, using a gauge system, and low and behold as the pressure begin to decrease the AC system kicked in all vents working and COLD air. My buddy explained that a system can develop a pressure lock not allowing coolant to flow through the system as it should and bleeding off the high side allowed the system to eliminate the vapor lock. The system has been working great since. This worked for me and hopefully will work for others. Oh yea I tried all the remedies posted on other sites such as disconnecting all power to allow the system to default, created areverse ground, etc.; none of them worked. There are three electronic actuators under the dash: one is for the defroser, one is for the bank of four passenger vents and one ( this is you) sends air to the two driver side vents, the two mid-dash vents and the two rear vents. Either this actuator is faulty, or there's a problem with the electrical delivery system; mainly, the whole climate control panel in your dash (dealer cost: about $700.00).

Thanks for the feedback!
There is a problem with the blend door for the passenger's climate control. The blend door diverts air through the heater box to the correct system ( ac or heat). It may by a …vacuum supply problem ( the climate system uses vacuum to operate the blend doors). It may also be a problem with the control head in the dashboard ( the thing with the knobs for heat/ac). The blend door may also be blocked by debris and can not operate properly ( such as a mouse nest, leaves, acorns, etc ).. EDIT:. The AC and Heat system DO NOT use a vacume system on the newer Regals (from 1997 on). If your car is this new, they have a known problem with the blend door motor, and can be repaired with a new part from the dealer. The part is fairly pricey thou.
Answer Open your hood and go to front next to wipers, on each side you will see a plastic wing , turn and lift off cover, it will be on drivers side.
AC uses electric power to transport the heat from the inside of the house to the outside of the house. AC uses a special gas/liquid that cools down when expanded and heats u…p when compressed. The gas is expanded inside the house, it cools down, takes on the heat from the air in the room. The gas is then moved outside the house where it is compressed, heated and releases the heat.

Probably Air Conditioning Unit. Unless that has nothing to do with what your asking.
1. Compressor 2.A fan 3.A gas, like freon, which vapourises @ a temp lower than room temp 4.The tubing/Piping An AC is a heat transfer operation.The gas(in the f…orm of a liquid) travels through the piping and it evaporates very quickly cooling the tube.The fan blows air across the tubes into the room, now to turn back the evaporated gas into a liquid so that it can be evaporated again, it is led into the compressor, the compressor is basically a mechanical component, which squeezes the gas back into liquid so that it can be evaporated again, this happens continously, and during compression, a lot of heat is generated, which is thrown into the outside atmosphere.This is the basic working of any refrigating device.
An 'air conditioner' is an electrical device or appliance that cools down or removes the heat from the air in an enclosed space by utilizing a refrigeration cycle. The a…ir conditioning system is made up of a compressor, a condenser, an evaporator, refrigeration lines and a couple of sensors. The compressor is the heart of your a/c system which takes the refrigerant (the gas) and pressurizes it so it will cool the air. It's run by an engine belt. An air-conditioning system uses a refrigerant gas like Freon to cool the air. Freon is placed in a sealed system and is then pressurized using a compressor. As it's pressurized, it gets hot by absorbing the heat around it. This hot gas then passes through a radiator outside to be cooled by the air outside which is cooler than the compressed gas. The cooled Freon still remains compressed. It is then expanded into another radiator where it cools off a lot as it expands. When air in your room gets blown across this cold radiator, it becomes cold too. This is also how most refrigerators and freezers work. Tushar kanta Rath Berhampur,orissa email@example.com
Your freon level is too low. Have it topped up and dye added to check it later for leaks. I had a very similar problem with a 2000 Olds Intrigue.
Why does AC of a 1999 Buick century with dual controls blow warm on drivers side and cold on passenger side?
Bad "blend door" actuator or stuck blend door on the driver's side.
Just look for small silver pipes, they'll have 2 little black plastic caps on them, it's perfectly safe to take them off; the smaller port under the cap is the low, the larger… one is the high. You usually find the low port somewhere more towards the windshield.
Why does the ac only work on passenger side while heat is on and blowing on the drivers side of a 02 trailblazer?
Answer Check your settings...the passenger and drive have TWO different temperature settings.
AC recharge port. is arms length down the left front of car on top of evaporaterator has a blue cap. Is very hard to reach your arm between the radiator and the motor to reach… this port. You should get an extention for the recharge hose. I burnt my arm because you have to have the car running to actually put the 134a in.
Answer A/C drain line is stopped up. Crawl under the car and find the drain line. Usually located on the passenger side near the firewall. Use a blunt objec…t such as a pencil to unclog.
whats it do. if it blows out cold on the passenger side and HEAT not just warm but f*cking hot its probly the vent door arm has fallen off or the motor is not moving. pu…ll the lover black cover off on the passanger side. a about 3 or4 feet long and quit a few screws but easy to do. look on the right side of the vent ducts you will see an arm and rod. see if its still hooked on and it moves when you change the temp from 60 to 90. sometimes it take 30 sec or so befor it starts moving. if it wont move then its not good. a new climate control programer. aka big computer box under the dash that contols the entier thing with driver comands from the dash display . is not cheap just take the rod from the vent and put it where you need it. in sumer time push it all the way in. in winter though your gona need heat on your side to so you will have to pull it back out.
There's a little door under your dash in the vent which switches between two ducts. The actuator for this door is either stuck or broken. It's a pain to get to, but any good m…echanic should be able to do it for not too much money.
The 1994 Buick Century air conditioning low side port can be found on top of the air conditioning compressor. The low side port will be labeled as the low pressure port.
AC runs fine on 1994 Buick Roadmaster when relay on passenger side of engine side firewall is jumpered. AC guy thinks computer is not sending signal because R139A once ran dry. How to reset computer?
if your pressure on the low side is ok which is 25lb to 45lb then check your low pressure switch if the pressure is too low then the switch wont close there for the curr…ent wont go to the relay there for it wont be powered.
