I had the same problem,to me it was the ac/heat door actuator,this turns a motor for the temperature contol, when its broken it ither stays at just one temperature or flips from hot to cold constantly , if it is this is its not a cheap fix. if you go to the dealer just the actuator costs you about $200 and labor is $800 they will tell you that they need to take the whole dashboard out and thats why it will take 8 hours. what i did was get one from the junkyard for $50 and install it myself,all you have to do is open the glove box and take out a 3-4 screwd weird shaped box (actuator) its a tight space but it posible to take out with out pulling the dash,it saves you $800. it took me about half an hour to change it.

Only way to tell if A/C Evaporator Core Orifice tube is plugged is by looking at A/C gauge readings , An if it is plugged you more then likely need a new compressor , they become plugged with metal particles from worn out compressor. Your best bet would be to take your vehicle to a qualified repair shop .

1997 Mercury villager, Air conditioner was working, now compressor kicks on and off, shows over charge in the red, why? Nobody added any freon.


high pressure is usually from heat not being removed from freon in the condensor. Usually it's because the cooling fan is not sucking air through the condensor. Check your cooling fan relays (3) in the battery box in front of the battery. Also, check to see if cooling fan has failed.
Does it work ok when the engine is cold and then quit after engine warm up? That would be a clue. When pressure gets too high, there is a high pressure cut-off switch.

Other posibility is a restrcition in the system. not common though.

1998 Nissa Sentra brake light & battery light come on


I had the same problem with my 96 Nissan/ infinity g20.
If I turned on the ac the brake & battery lights came on, the AC fan would work but the air did not blow cold. Disconnected the battery for a few hours to reset the computer. That solved the problem.
Now, no lights, and the AC blows cold.

1998 Honda Accord interior ventilation fan has stopped working.


they are right the air conditioner has nothing to do with the fan running .. your air conditioner is operated by a pressure switch .when it gets low on freon it will not come on, which saves your compressor. your fan only blows the cold air the air conditioner puts in to the coils located inside your dash. which the blower then blows the air into the car.. now you are on the right track look some more you will find the round motor under that dash near the glove box and its held in there with usually 4 small bolts. and removal is easy if you can locate it.. one wire and 4 small bolts and out it comes .. you should be able to get one at a local parts store ..
