Hi RB,my 96 volvo 940 glt have almost the same symptom,but the low side line is cold n sweat. Compressor keep running all time,at idle or hot weather it still not cold inside even when car is moving. Only work at night or rainy weather.🙏
My AC blows hot air when in idle on a hot day. I brushed this off as my car just being really hot with leather seats + black car. But when I drive it cools down. Replaced the cabin filter and the AC feels cooler BUT it’s still really hot on idle and even after around 5-10 minutes in idle it’s hot. I’m planning on buying a recharge kit tomorrow to get an idea on my pressures. I am also going to check my fans before to see if they’re running. I have a VW passat cc 2010. Any comments? One thing I noticed today was it was blowing cool air however when I turned on circulation, it goes to warm. Any answers to this particularly would be really helpful. Thank you!! I appreciate you still answering comments!
@@RBTheMechanic thanks for the quick reply, Bought a can to check the pressure (i know it’s not accurate) but it’s in the yellow at 60psi one slip away from being in the red. Taking it to the shop on monday, any comments about that?
Had similar issue, for me it turned out to be one of the fans by the radiator … once replaced the problem was solved for about a year till I had to replace my compressor
Had the same issue . A hose broke i change it my self pull a vacuum recharged it and still only blows when running . Low pressure 55 psi high pressure 150 .
I have a 2008 nissan pathfinder. It only gets cold when driving speeds at like 50mph+ i just put a full can of r134a in there any recommendations please?
It’s never good to use cans u have no clue how much u have in there now too much. No good! So I would recommend re servicing the system using ac machine recover to see how much was in there compair it with how much capacity it got and the. Vacuum and recharge correct amount
03 chevy tahoe with dual system. I paid to have new compressor, dryer, condenser and flush lines, orifice tubes and still wont cool right on a hot day especially at idle. Im taking it back to them for the 3rd time on Monday. They have a great reputation and are willing to keep taking it back to find out what's wrong but i'm frustrated at this point and have so much money into this repair. Not sure what to do.
Same. I replaced with genuine Honda Denso compressor, condenser, high pressure line & Denso expansion valve & still not strong ac. Maybe it is just too hot here in Phoenix.
I had a vehicle that wasn’t cooling down properly at idle, turns out it was one of the fans by the radiator… when in motion, the air passing through the radiator was enough to cool the air down a bit but at idle it got really hot, replaced fan and problem solved until my compressor gave out and had to replace that a year later… maybe you have the same issue?
I have the same issue 2013 , i just changed ac com with a reman on ebay but not cold enough and yes wen car is on the road does get colder but still not cold enough i checked leaks with the machine and nothing was showing of any leak
Hey how’s is it going, I have replace my fan blower motor, fan blower resistor and a/c pressure sensor my truck has Freon new ac line and orfice tube. When is hot outside my truck does not cool down only when is cloudy or cold outside my ac works. I drain my evaporator and after draining it still not working. By any chance you might now the problem?? Last thing I think it could be is replacing my evaporator. I have a 2000 Chevy Silverado
Generally this is a major problem, probably a leak. Easiest way is just change the whole system. If the leak can be found then you are in luck but its usually at the cooling coil which is usually inside the dash board. So if u have to open up the dash board which is a major job, might as well do the whole system.
Hey RB , I like your video. My Toyoto Corolla 2015 ac has never been serviced. It’s starting to act up not getting as cold, I checked with a gage from Walmart and it’s showing full. Do u think I might need to have it recharged? Thanks.
I would recharge it service it with ac machine recover vacuum for 20 minutes then recharge correct amount oil and Freon also clean out front of ac condenser and check fan operation
@@RBTheMechanic Hey Mr RB, thanks for replying.I got some manifold gages and check my AC, it’s around 95 dg here . I put in a 12 oz can of 134, low side 45 psi, high 210 psi. Now it blows 40 dg going down the road, and 60dg at idle. Rev up the engine it gets colder. It used to blow colder at idle. It’s 8?yr old , never been serviced. It’s been 1 week and it’s still showing the same pressures. I don’t know where 12 ozs went to , but it was gone. Please any idea what I should do to get it blowing colder at idle or just don’t worry about as it blows cold while moving? Thank u .
@@RBTheMechanic Yo k. Thank u. If I was around u , I would let u do it. But I’m in Miss. I don’t know what it cost, but when u get a chance, let me know what u would charge me. Kinda give me an idea. I will let u know what happened after I get it done. Thank u again RB!!!
I have a 2015 chevy suburban and my entire AC system is running fine but on hot days, it doesnt cool below 70 or 60 and then at night, it goes low to 40. In Florida. System is not low on freon or has any leak. So what could it be? Thanks in advance for any input.
@@hienowens188 it dosent buil pressure at night. It dose the same thing it’s just cooler at night and it stays cooler get cooler fast because they not sun beaming
Will somebody that has a channel on UA-cam of dressing air conditioning please explain that on a lot of cars especially the Imports but not only the important there is a compressor control valve in the compressor the symptoms would be the AC gets a lot warmer at idle because of a faulty AC compressor control valve that is in the compressor and don't get fooled there are some cars that get warm sitting at idle because the cooling fans are not coming on but just so everyone knows if you have an AC system that the compressor is engaged so to speak one hundred percent of the time even when the AC is off and you have almost perfect AC gauge readings it is going to be that valve in the compressor only
Guys if anyone can help i have an 06 Toyota sienna, when cold air is on with NO ac on why does the air come out hot when im park but when i drive it comes out warm not cool. If someone can please help me. Or advice
It maybe has low Freon when u push the gas peddle engine spin faster and ur ac compressor spin faster that could be one reason low Freon but with high revolutions it’s able to cools pump faster
@@RBTheMechanic2011 Ford Fiesta. Air conditioner has always been cold. I replaced the cabin air filter and since then the air condition blows cold as it use too but now fluctuates. Sometimes at a stop and even sometimes going down the highway at 60 mph. It can be 5-15 mins apart or longer?..

It might be low on freon u have to start with checking pressure if it’s low the donac service with ac machine

Changed too much for ac not to work did u check ac diaphrams opening door I think ur car had vaccum line to control diaphragm

How often is the condenser fan the culprit and not low Freon?
Fan is rare

Either ur system doesn’t have Enough Freon or ac compressor doesn’t build pressure so I would start with reserve the system
@@RBTheMechanic but why does it build enough pressure at night and not daytime when its hot outside. What do you mean with reserve system? Thank you

Guys if anyone can help i have an 06 Toyota sienna, when cold air is on with NO ac on why does the air come out hot when im park but when i drive it comes out warm not cool. If someone can please help me. Or advice
Is ur blower motor off?
Why does my AC only work when I accelerate
It maybe has low Freon when u push the gas peddle engine spin faster and ur ac compressor spin faster that could be one reason low Freon but with high revolutions it’s able to cools pump faster
Okay I did this the shop filled it up and added a leak, nothing found ? The ac works on like days like 80 out but 90 it stops. Any ideas?
Check refrigeration pressure
Weak compressor
Low refrigeration
