Santa FE SM (2001-06) :: AC Starts Blowing Warm Humid Air In Stop-and-go Traffic

This weekend was a nice high 80's low 90's. My AC is usually ice cold. However now that the weather hit that high, when we are in stop-and-go traffic, the AC starts blowing warm humid air. I do see the temperature need creep a bit higher than the normal range.

Once we start driving, after a few minutes, the climbs back down and the cold AC returns. Turning the fan speed down, or turning the compressor off, then on again, seems to work.

What could be causing this? A friend said he has this issue with his car claiming the engine is the issue, not being powerful enough to keep the compressor running right, is that possible?

Santa FE SM (2001-06) :: Overheating / AC Blow Warm And Hard Start

I have a 2004 Santa Fe and have recently noticed the following problem. When it is hot outside (95 degrees) and car has been idling for a while, suddenly the A/C will start blowing warm air and the temperature gauge will start creeping up above normal. It hasn't fully overheated as when this occurs, I shut off the A/C or start moving and it returns to normal temperature. The A/C will then work properly again. Also, when this happens, if I turn the car off and then try to start it again a few minutes later, it is very hard to start but eventually starts. It can easily be reproduced, but I want to try to understand possible cause before taking it to a dealer. I was thinking maybe fan going bad, or fan switch.

Ford Super Duty (1999-2016) :: 2001 - Long Hard Starts No Matter What The Temp Is Outside

My truck is 2001 F250 with the 7.3 I have AFE intake, TS 6 position chip, Stage 1 Auto Tranny, 4in Exhaust all the way down. New glow pugs as of last week as well as uvchs and gp relay. Also has a new hpop line. New compression sleeves for fuel lines, riff-raff fuel banjo bolts and fuel pressure regulator.

I am having a hard start issue no matter what the temp is outside, unless it plugged in. Once it starts its good unless it sits for more than 5 hours.

Batteries have tested good, glow plugs ohm at 1.3, gpr 12.83 at batt side- once on it 11.9. All fuses are good. HPOP res is showing at about 3/4" down from top.

***Wires going to the MAT sensor are showing through at the connector, not sure if this could be a problem...if so why???

****Noticed some oil in the ICP, cleaned and unhooked will check start tomorrow to see if this works with long start as truck is plugged in.

Will also be putting a new fuel filter in and double checking oil level in the am. I do not have a scanner tool and am doing the best I can before I take it in to ford to diagnose.

Chevrolet - Malibu :: 2003 - Hard Start Then Won't Idle

My car will start but die. it either wont turn over or if it does, the engine goes right off. The radio and lights work though. the throttle & iacv were all good. i got it towed and the mechanic brought it in his garage at end of the day. He said it wouldn't start so they left it for monday. The thing is that my ignition sometimes gets stuck and leaves radio & interior lights on. So when they tried starting car on monday, it was dead. They put different battery on & it started right up. they said everything else was ok. they charged my battery & I had no problems. until today, 3 months later, same problem. both times it happen when I am leaving work & both times it was raining & cold. Could my battery be bad? also wonder if place really checked everything out likethey said.

Chevrolet - Malibu :: 1999 - Hard Clunk When Put Car Into Reverse

I have a 1999 chevy malibu with a 2005 chevy impala motor in it. Recently I put my car into reverse and it made a hard clunk and went into reverse. Later on that day I tried to go into reverse and it will not reverse. I had to have 3 people push my car back in neutral. However, in neutral I am able to press on the gas and drive forward... This is an automatic transmission. Am I just screwed and need a brand new transmission?

Chevrolet - Malibu :: 2005 - Idling Hard In Reverse

My car is idling hard in reverse, and the mechanic said, in fact, a problem with the transmission (a turbine?) Well, a new transmission costs much - so, not much savings there. I was told to try some simple fuel injector cleaner first. Chevy Malibu Classic, 2005....

Malibu - Chevrolet :: 2003 Starting Idling Really Hard - Cylinder Compression

My 2003 Chevy Malibu recently, out of nowhere, starting idling really hard. It shakes and jumps quite a bit when it idles, much like a car creeps when it's about to run out of gas. It drives fine at speeds over about 10-15 mph, but then when it slows down it gets shaky and bumpy.

Malibu :: 2004 - Intermittent Battery Light And Dings Randomly During Hard Acceleration

I have a 2004 Chevy Malibu Maxx that randomly dings and shows me the battery light.

It usually happens when going uphill or during really hard accelerations.

It is also showing OBDII code P0621.

The car has no other issues. Always starts, always runs well.

What causes this problem? Where should I start looking? I'm thinking it's probably a bad connection somewhere.

Passat (B6) :: AC Slowly Starts Blowing Warm Air

If my car get really hot, it initially blows cold air (the way it should be) for 5-10 minutes, but then it slowly starts blowing warm air until I get the full heater going for about a minute, and then it goes back to cold air, sometimes after 45 minutes the cycle repeats. This does not happen every time, this year I had it happen about 5 times.

Honda - Cr-v :: 1997 Starts Fine Then Dies Only In Warm Weather

Our car starts, then dies. It starts fine, then dies. This only happens in warm weather, which we have finally been experiencing in Northern Illinois. It eventually gets to the point where we can drive it, but then might die at a stop sign, or it can go the rest of the day and not have any difficulties. I know later models have timing chains, not belts. Does our car have a timing belt problem or maybe fuel pump? And why only in warm weather?

Civic - Honda :: 2003 - AC Works But As Soon As Day Gets Hot It Starts Blowing Only Warm Air

If the outside temp is cool (say below 75) the a/c works, but as soon as the day gets warm it starts blowing only warm air. I took it to the Honda dealership and they said that it was low on freon and that it needs a new clutch and a new coil. They recharged it and added dye. A week later I took it to a good independent shop that specializes in Honda repairs. They said that the compressor has power and ground and is full of freon and dye but they found a bad thermal switch and that I need a new compressor. I have no understanding of car a/c systems and thus don't know which repair sounds like the right one (if either) based on the diagnostics that have been done.

Ford Ranger / B-Series :: 1995 - After Warm Up Starts Idling - MAF?

I have a 95 4.0 EFI inside of my 83 Ranger. Once the motor warms up, it starts to have an idle issue. I have to press the gas, in order for it not to cut off. Here is a video I posted a while back. A person suggested that it could be the MAF needed to be cleaned. I did that, and it did not work.

Ford 6.0L Power Stroke Diesel :: Starts Then Won't Start When Warm Outside

Left on hunting trip last Thurs. Blew tire on trailer 6 miles from home. Shut off truck. Went to restart, cranks only. No codes. Towed home.

Thought it might be a fuel filter problem. Had just changed oil/filter and fuel filters prior to trip. Checked filters, upper bowl was low. Turned key to on and bowl filled up. Noticed filter wasn't snapped in lid. Also checked lower filter.

Drove it to work this am. Turned off truck and tried to restart to check. NO START-Cranks fine!!!

Jeep - Cherokee - Airconditioning :: 1998 - System Starts Blowing Warm Air And Stays That Way

It works great for the first 5 minutes and gets icebox cold. I can almost see my breath then the system starts blowing warm air and stays that way. I've had the coolant recharged and the shop tells me there is nothing wrong with it. Of course it works for them.
