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).

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.
the duct is probably clogged up, sometimes leaves, or critters like mice get in there. another possible reason could be that the diverter is stuck in the closed position….
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.
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.
When you run the AC in your 1995 Buick Riviera your back floorboard behind the passenger seat gets wet what is causing the leak and how to fix it?
Answer It's very possibly a function of condensation. Check for multiple evaporators. If there is more than one in your Riveria, the second will be somewhere in the are…a where you are getting the water. If that's the cause, clear the condensate drain and that should clear the problem. This is a very interesting question. I have a 1995 Riviera, in excellent condition, and noticed water beneath the passenger seat and also on the carpet directly behind the seat. After soaking up the water and drying it out thoroughly, I went through a car wash the other day and as the water was spraying underneather the vehicle, immediately I felt the carpet under the passenger seat becoming very wet. I assumed that the water was getting in somewhere under the passenger seat but after the car was put up on a hoist, the meachanic couldn't see where the water was getting into the car under the passenger seat. He has suggested removing the passenger seat and lifting the carpet to see where it might be getting in. He said there are two seals located under the seat with caulking around them and he can only figure that the caulking has let go. However you are relating this problem to the A/C and now have me thinking. Do you think it has to do with the car wash pressures pushing its' way in under the passenger seat or are you thinking that it has to do with the A/C?
behind the right front wheel well
Answer The actuator that controls the diverter door needs to be replaced.
What is the technical name for the black box up under passenger side that controls ac blower on a 98 Lincoln mark 8?
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.
If your compressor is properly diagnosed as bad. Then you can expect to pay about $900 for a correct repair.
Low refrigerant? Blown fuse? Bad compressor?
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.
about 6" from blower motor "towards pass.side"has a four plug and two plug connection on it
Why does the ac vents work on the passenger but not on the drivers side of a 2001 Pontiac Bonneville?
Your need to add more r134a Freon. When the levels are not sufficient to cool both sides the car default sends all the cold air to the passenger side and not the driver'…s side.

You charge the ac system on a vehicle through the low side port. There is alot of DIY (do it yourself ) tools in the market for you to work on your ac system. You can find a l…ot of helpfull information on www.idqusa.com.
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.
