Air conditioner wont turn on

if the clutch is working then the fuse will most likely be ok as well
when ac units stop working , it can be put down to a gas problem or lack of gas from a leak in the system
have an accredited ac specialist shop check the system for leaks and proper diagnosis.

If coolant is slugy then heater core might be gone bad. Ac will always leak water in that area

Air Conditioner No air coming from air conditioning vents

1. Check the air conditioner fuse and replace as necessary.
2. Air conditioner system discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
3. Air conditioner low pressure switch defective. Replace switch.
4. Air conditioner fan resistor pack defective. Replace resistor pack.
5. Loose connection, broken wiring or defective air conditioner relay in air conditioning electrical circuit. Repair wiring or replace relay as necessary.

see if that vehicle came without A/C. If so ck for the belt availability and see if it can be put od bypassing the compressor. At the least, disconnect the compressor clutch wirin g so the A/C will not function at all. until you can manage a the cost of a pump. Good luck, Ned

Chances are that if nothing over the winter poked a hole in the condensor, 1 or more of the O-rings that are at each joint / connection, has dried out therefore allowing the refrigerant to leak past the seal. Have a qualified tech check it to be sure. The cost may be a minimal 1.

Your car has a fan controller box, it can be self tested by the dealer, suggest u have this test run, one last thought have u hooked power to the fan motor to see if it is working, they do burn out as they run the most of the two fans.Is the compressor running?

your a/c compressure probably went south you cancheckthat by manualy trying to turn the comp.clutchby hand or have a trusted mech.check it for you.

HI. Here is a complete check list that will help you trouble shot thsi issue. You will find the problem in one or more of these areas stated below.

1. Check Drive Belts - The air conditioner utilizes a drive belt that supplies power to rotate the compressor, which is basically a refrigerant pump. If the belt fails the compressor has nothing to drive it, inspect and replace as needed to restore operation. If belt is intact proceed to the next step.

2. Check for Compressor Clutch Engagement - Turn the air conditioner to the "on" position and set controls to the coldest setting. Start the engine and allow to idle. Then open the hood and inspect the clutch at the front of the compressor, is it turning? "Engaged" if so, the system has enough refrigerant to activate. If the system is low on refrigerant it will not work properly. In this case an air conditioner recharge kit is needed to recharge the system. If the system is low on refrigerant it could cycle on and off, making a ticking noise. If the compressor clutch is not turning proceed to next step.

3. Inspect for Refrigerant Leaks - If the system has a large leak and no refrigerant remains it will not activate. First test system for a static pressure charge, with the engine off attach an ac gauge to the low side pressure port and check the state of charge. Depending on outside temperature there should be between 50 psi and 80 psi. (Cool and warm). A refrigerant leak detector is needed to inspect for leak, but if you do not have a leak detector there is an alternative method. The air conditioner system is designed to run with oil suspended in the refrigerant to lubricate the system. Check for oily residue outside the system by inspecting all hoses, compressor, condenser, evaporator or receiver drier and replace any component that has failed.

4. Inspect Fuses - Check under dash panel and under hood power distribution center. Replace failed fuses as needed, recheck system. If the new fuse fails when reinstalled a short circuit is present and requires diagnosing with a wiring schematic, follow circuits to locate short, repair as needed and recheck system.

5. Check Temperature Control Vents - The vents inside your car are controlled by a cable, electrical servo or vacuum servo. If the temperature blend door is not functioning properly it will cause warm air from the heater to exit the vents. To check this start the car and allow the engine idle, next turn the blower motor speed on low, switch the temperature control from warm to cold while your ear is close to the vents. You should hear the door move inside the heater box as it swings from open to close. If not, insect for a vacuum leak or a shorted motor in the servo, repair the leak or replace the servo motor.

1. check your fan belt, if your fan belt is in the normal position and no problem.
2. check your compressor and also check the clutch, it is locate right in front of the compressor, when you turn on your air conidition, the clutch should be turn with the fan belt. If it is not, that means your compressor had problem.
3. check fuse.
4. check the freon small flow window see if the lique bubbling too much, if it is means you need fill up R-12 freon.
5. you probably can not do it yourself, in case if you need freon and your compressor is completely empety, you need a special tool to **** the air out first and than fill up freon.
6. if your air condition is leaking,and you have to fill up a can of special check leaking freon with red colour first, until you find the leaking parts, fix it then you can fill up freon

If the air conditioner blow warm air,

1. Open the hood and check the fan belt first, sometime the fan belt broke caused the compressor stop to work, if the fan belt is good, check the compressor see if the center part turns, if turns, that means the compressor is o.k.

2. If both work fine, check the air conditioner small window see if there is bubble, if you see some bubbles in the small round window, that’s means your air conditioner lack
R-22 Freon.

3. before you fill up the Freon, check the leaking, if leaks, fix it and then fill up the Freon, the best way is to ask some professional auto air conditioner repair shop to help you.


Hope this can help you.
