There are several things that may go wrong with an AC system, from leaks, to grime build up to mechanical failure of certain parts. Before you hit get stuck in the heat make sure the AC is going to keep you cool. Here are common reasons a vehicle air conditioner fails. One of the most major causes that warrant air conditioner repair is an AC system leak, which can be very difficult to detect. The refrigerant used in AC systems evaporates on contact with air, so an ultraviolet fluid must be introduced into the system to determine if there is a leak or not and to find the location of where it is. This test is usually performed if your AC system experiences low refrigerant pressure. While an AC leak is a common culprit of no or insufficient cool air, other reasons include a loose or broken drive belt, a clogged expansion valve or a blown fuse. However a broken compressor or slipping compressor clutch can also cause a lack of cold air. Each of these will need to be serviced by a professional auto mechanic.

If you experience AC issues while idling you need to ensure the electric fan motor is working. Some vehicles have two, one for the air conditioning condenser and the other for the radiator. In places like Texas where hot weather is frequent, it is important that both of these fans work properly so that your engine stays cool, along with yourself.

All Tune And Lube Tyler Blog 00 ML430 - AC Problem, blowing air, but not cold *Air Condition Problem * No cold air could be a/c switch Originally Posted by Detari_SR I thought there was something wrong with mine too...turns out there was no freon left in my AC...you can buy a recharge kit at any autostore (autozone, murrays, pepboys), plug it into the lower line, and charge it... Look for AC recharge kits in stores.... I hesitated responding becasue I have a 05 and the climate control system is quite different fom yours - at least the way it works. In any case, I had a similar prolem with my 05. In my case, the insides would fog up terribly on rainy days, there was barely any warm air and the cold air wasn't there at all. It was diagnosed to a faulty temperature sensor. That would require taking out the dash and I wasn't too happy. The looked further and found out that the control unit (I have no idea which one) that sends data to the temp sensor was the culprit.

It was replaced and I have been having good air since March, I believe. If you have to add freon, there is a leak somewhere you need to get it fix to avoid costly repairs in the future. My A/C worked fine until i hooked up my battery wrong ADDING TOO MUCH FREON CAN RUIN COMPRESSOR I am sure you probably already know that adding too much freon can ruin the compressor. I mistook a problem for low freon and added some to an 85 MBZ wagon we had about 20 years ago and it caused the compressor to seize up. An expensive mistake and I should have known better. It is definitely better to use gauges to determine if the system is low before adding in. Some who do AC service have a dedicated machine that vacuums all freon out of the system and then they put back the right amount so there is less chance of a tech misunderstanding the gauges.

If it doesn't then you are probably low on refrigerant. If it does, then wait a couple of minutes and go to the fire wall and touch both aluminum pipes, one should be cold and the other hot. Originally Posted by Maj. Dundee I think the control knob is messed up because cold is hot and hot was cold, now it seems like like the switch moves too freely That might very well be the case, but was it too much trouble to see if the compressor clutch was working and feel to pipes on the firewall? I am currently having a problem with my ac. When i press the A/C Button the compressor engages for a minute then it shuts off (pulley stops spinning). is it possible that it may be low on refrigerant? I could not tell if the pipes were hot or cold, or it wasn't noticeable. when i press the button again off then on it does not engage again unless i completely shut the car off and on to try it again. I also noticed the fans in front were not spinning. R&I Fuse & Relay Box.pdf (56.1 KB, 2182 views)
