2003 Ford Windstar AC is not working. It only blows out hot air. The blend door act. works properly(We have already tested it). There are properly freon in the Vehicle. We are at a lost. Please help


Can you tell if compressor clutch is engaged? If clutch isn't engaged only the belt pulley will be moving and the compressor clutch is not engaged. If not engaged, no ac.

Can you check for applicable hvac codes? To check codes, your-self, at the least, you need an obd2 code reader, that will check manufacturer specific codes as well as po.

I haven't looked at your wiring, you could probably check voltage and ground for compressor, hvac on.6158ef87-8677-4b29-952a-e287698970b5.jpg
In the diagram, you see applicable fuses--clutch relay-- the top wire at ac clutch is voltage--black wire is ground.

Why won't the AC work after the engine warms sp?


You'll need someone to check the electrical circuits to make sure the compressor is working and then check the blend door to make sure the heater is not on.
If the compressor stops running it could be the compressor clutch or a relay.

Ac compressor relay location


If you suspect low refrigerant you can use paperclip to jumper the low pressure switch momentarily. Relay should be in main fuse block under the hood, I think.

A/c won't work


What I do that will cut the distance the short or break could be and also eliminate that it is low R134a is to find the Pressure switch ( mine is just off center toward passenger side of firewall connected to the desiccant dryer unit).. So once found you unplug it, it will have 2 connections in it I take a short piece of wire strip it so just enough wore sticks out so you can make a circuit. Then start vehicle and turn on AC. If the compressor clutch kicks on then it is either a faulty switch or low R134a. I now have a gauge so I can just connect my guage and test that way but I have found on a ford when off the pressure seemed good but the killer was when compressor was running the pressure would drop fast to just above switch setting then take about 2seconds to fall below telling me the system is low. but using both a guage and the bypass would be best method in future. But if you do as I mentioned with wire it will either be compressor on or not regardless of switch or pressure in system. I will look back to see if it engaged clutch or not as I have method fr testing clutch also

The pressure switch is right next to the battery negative terminal. To bypass the switch, remove the connector and use a paperclip to jump the terminals inside the connector. By the way, you need to put oil in the system, or the seals will quickly dry out.

2006 Honda Odyssey AC Compressor not working


HI. Here is a complete check list that will help you trouble shot this 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.

2003 ford explorer ac compressor does not come on. fuse is good, blower works also,


It is probably either a bad compressor clutch or the system has lost its fluid and the low pressure switch is keeping it from coming on. If you track the AC lines on one of them you will see a sensor with a plug connected to it. Start the car turn the AC to max, blower also. Then unplug the connector on the pressure switch and jump the wires in the connector. Use a flat head screwdriver if the connector has exposed pins or a paperclip if the pins are inside little tubes. If you do this and the compressor kicks on then you have lost your refrigerant and have to bring it to be leak tested. If it doesn't come on then it is probably the AC compressor clutch.

AC is not working properly


this first to do is check wiring to compressor clutch,when ac is not working check the ac clutch it should be engaged,test for power and ground at ac compressor clutch, you may have a bad wire to clutch or a bad compressor clutch,8226523.pngc97e168.giff41b56b.gif672ce29.gif

Air Conditioniong not working


U may be low in Freon gas.
When Freon is low there's low pressure switch that will prevent A/C compressor clutch from engaging to protect it from failure.
So, first check Freon pressure & any leaks form lines & hoses fittings.
Even if the fan is working, that doesn’t indicate proper compressor OP'S.
Look at the compressor front side you'll see the clutch stationary while the AFT pulley moving.

Then put air-condition compressor switch to ON (Engage),
You should see the clutch engage & start rotate,
If NOT, this is very clear indication u r low in Freon.
