Why does my mazda mpv stall when ac is on but it runs fine when the ac is dissconnected


Make sure that your drive belt and ac belts are tight. A loose belt will look like many problems. Also could be your ac compressor. They have ac compressor lubrication in a can just like the freon. You can notice the extra strain the ac puts on the engine when you turn it on and especially at idle. So 1. Make sure belts are tight and in good condition, if not replace. 2. Check freon level in ac. If freon level is okay add ac oil conditioner.

AC on my 2004 Buick Lasabre is not working correctly as I had my Freon checked and it is very Good and when I pur My AC on Low it works but if I try to use it on high it does not increase the cool tem


sound like to me that need more freon there is a few ways of doing this so best way is with car running with gauge ac on it should read in the green part of your gauge if you have a gauge from a normal freon can from walmart ect. even so its in the green you might have more air then freon on the system and might have to take it to some place that does ac and ask them to re run it through so they can take the air out also vechicals have a orifice tube that can dirty and slow down things like cooler temps and this is helps remove air from your system lask i check so that might be somthing to look into also if you change this you should have the car refilled with freon for a profionnal to get your maxmal proformace from your ac not ouf of a can you can also have them put dye in there to find leaks to save you money in the long run good luck

My air conditioner quit cooling. i was going to add freon but cannot find the low pressure port. it has 2 ports on the same line and my fill tool will not fit but one. the freon will not go in.


The ports are keyed - you found the proper port if you have the proper hose. If the Freon will not go in - and you have complied with all the package instructions ... right? ... Freon is not your problem. Going much beyond what you have done already is dangerous. Please have your AC looked at by a licensed AC Service Mechanic.

Thank you for your question @ FixYa.com

Ac compressor on 99 isuzu rodeo turns on and off . already filled with freon. air is cold but not consistently


Does it have the correct amount of freon, it can still blow cold with the wrong amout of freon, this will damage the compressor,you may also have a bad cycling switch or bad high preasure switch and even a bad connection to ac system,this first thing is to make sure the correct amount was installed,

How to remove a ac/compresor


To Remove the AC compressor you first have to have the freon vacumed out before you break the lines. If the freon has already leaked out then you dont have to worry about it. The AC generally has four mounting bolts securing it to the engine loosen those four bolts as well as the two AC lines and the belt. If you are trying to replace the AC compressor yourself you will need to know this is a complex job. Most places will not warranty the compressor unless you also replace the accumilator as well as the orfice tube or expansion valve which ever the case may be.You will also want to flush out the system with AC flush and while you are removing each part be sure to replace the o rings associated with each part. Once you have all the parts back together then you need to have the system vacumed out to remove all the moisture this is crucial other wise you will have prmature failer of your compressor. Once all this has been done then you can charge the system back up. Oh as you remove each part plug the lines to prevent contamination from getting in there. The compressor may or may not come pre oiled so youll need to oil the system back up.
