Sounds like there is not enough r134 coolant in the system and when your slowing down the compressor stops turning. Have someone add some coolant and you should be ok.

I have a 2008 mercury mariner and the AC has stopped working. Fan only blows on 3 and 4. When it's 80° And zero humidity, cold air blows, however, when it's over 80 hot air blows.


Your best bet take it to ford an have diagnostic's preformed ! May have DTC'S - diagnostic trouble code that would pin point the problem , Could be a duct temp sensor problem . You wouldn't want to take the dash apart to just replace this sensor . The Tech there can look at scan data of all the climate control system componets .

This is caused by the low pressure AC compressor cycling switch, it is a very cheap part and located in the larger of the two AC lines coming from the AC compressor.

you have moisture in the system this causes your expancion valve to freeze up an stop working, thats why it works for sort time and when it de-freezes stars working again. you need to do a EVAC & RECHARGE with a good AC service equipment, specially attention to pull vacumm por at least 20minutes so you get all moisture out of the system.
Good luck

There is moisture coming out of the AC vents on my daughters 2006 s40, usually during very hot weather and not until the car has been driven for several miles


The drain on the evaporator is stopped up,look for it directly bellow the ac lines ,where they go into the car,under the hood,it will be on the bottom of the blower box,use air pressure to blow into the drain to clear it out.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck
