Chevrolet - Tahoe - Airconditioning :: 2004 - HVAC Works Intermittently?

2004 Chevrolet Tahoe that has the dual climate control features. Some days the A/C blows cold on one side and hot on the other with it set on the coldest setting. Another day it blows cold on both. Then you guessed it a few days later it goes back to blowing hot on one side and cold on the other.

Chevrolet - Tahoe :: A/C Malfunction - No Heat In Rear Most Of The Time

I have a 2004 Tahoe that the rear heat and A/C is giving me fits. I was getting no heat in the rear(front was fine) so I checked the heater hoses to the rear of the vehicle and they get hot. So I replaced the blend door acturator in the rear. That seemed to work for a little while but now it is 50/50 whether you will get heat in the rear.

Chevrolet - Tahoe :: 2004 - Gas Mileage Dropping On V8

I have a 2004 Chevrolet Tahoe 2WD with the 5.3L V8. Tahoe has 134K. At about 125K miles, I replaced air filter with a K&N, new OEM spark plugs and spark plug wires. The Tahoe has been running great and was getting normal mpg until recently. 15mpg in town and 17mpg on the road is what I normally get. The last 3 fill ups my mpg has been below 13.5mpg. Car still runs great but at 13mpg it's starting to hurt a little financially. Weather here in NC has been normal, my driving conditions or habits have not changed, etc. What could be causing my mpg to drop by so much while the suv still rides smooth and straight?

Chevrolet - Tahoe - Transmissions :: 2004 - Front End Of Car Started To Shutter While Driving

I have an '04 chevy tahoe, only 70k. Very recently the front end of the car has started to shutter while driving. This happens when I am going generally above 45mph- more so going up a hill. It feels a little bit like I am driving over unevenness/ripples in the road- even when it's smooth flat pavement. When I take my foot off the accelerator and just coast the vibration stops. I got new tires put on front so it is not a wheel balance issue. The car does not pull left or right either like out of alignment. And the engine rmp's do not fluctuate/strain when the shuttering starts.

Chevrolet - Tahoe :: 2004 - Front A/C And Heater Stopped Responding To Level Knob

I have a 2004 Z71 Chevy Tahoe with 192,000 miles that runs great. The issue I have though is the electrical system is going haywire (no pun intended). The front A/C and heater stopped responding to the level knob, therefore doesn’t blow, the dash lights will periodically dim and go off, the horn doesn't work when I want it to, and the A/C would sometimes blow warm air when it did work. The A/C used to work on all levels of the dial, and then over time, level by level, they stopped working; however, the back blower works well on both A/C and heater, which is operated by the overhead control knob. I open the front vents to allow outside air in, rather than recirculated air, and the air coming out of the vents is A/C air, but it only blows when I'm driving of course.

Chevrolet - Tahoe :: 2004 - Grinding When Turning Right / Braking - Shaking At Highway Speeds?

I drive a 2004 chevy Tahoe and have had this problem for about 8 months. It started out very faint and occasional, but has now escalated to loud and consistent. So it ONLY happens when turning right. I've tried to replicate it when turning left and had no success. It happens when I am turning fairly hard at a decent speed. ex. Pulling into my driveway. I've already checked the wheel bearings and Ball joints.

Another thing is that the ABS light is on sometimes when i start the car and comes on every time i turn the steering wheel all the way to the right. It also has a problem where it will shake almost uncontrollably when driving at 65+MPH after hitting a bump or sometimes just randomly on a smooth surface. We just got new tires and balanced them. It did the same with the previous set we had. I know I'm asking for a lot, but where to start?

Chevrolet - Tahoe :: 2004 - AC Blowing Hot On Driver Side And Cold On Passenger Side

I have a 2004 Chevy Tahoe with the 4.8L V8. My A/C is blowing hot on the drivers side and cold on passenger side. There is only one controller, not two. What the problem could be...and I'm scared to ask...how much it may cost to fix? It has happened only one other time and that was a year ago, and it has worked fine since then until today.

Sebring - Chrysler - Fans - Airconditioning :: 1999 - Fan Speed Lost Control In Both Heat And A/C Settings?

Have lost all fan speed control in both hot/A/C settings. Resistor pack checks out okay. Fan runs when voltage applied direct to it. Have +12v into r-pack. Fuse (inside) okay. The fan speed is controlled by adding resistance between Fan & ground. Thermal cutout part on R-pack okay. How do I test out the relay (in engine compartment), and could that even be the prob? Will look at dash switch next. Any schematic for this?

Honda - Pilot - Airconditioning :: 2003 - Heat Starts To Blow Out Of Upper Vents When AC Is On Automatic

Problem: About 10 minutes after driving, the heat starts to blow out of the upper vents when the a/c is on automatic. The heat comes out even if the outdoor temperature is mild (55 – 70 degrees Fahrenheit) and the cabin temperature is warm, which heats up the SUV quickly making it very uncomfortable. Turning the a/c off tends to somewhat solve the problem some of the time, however, occasionally hot air creeps through the vents even with the a/c off. The a/c often makes a gurgling sound whether it is on or off. I noticed today (2/3/12) that the back vents are not affected by the problem, so the very warm air is only coming from the front upper vents.

Hyundai - Heating :: Burning Smell When Heat Is On

Car: 2013 Hyundai Santa Fe

Problem: We have a sweet burning smell like antifreeze or oil coming from the vents when the heat is on.

We have taken it to 3 mechanics and they can't figure out what it is. We expect the heater core is going bad, but the symptoms do not fully match what we are experiencing. We do not have any leaking antifreeze, nor do we have any windows fogging. They also ran a pressure test which came back normal.

Civic - Honda - Heating :: 2005 - Heat Temperature Varies Regardless Of Where Set The Dial

My 2005 Honda Civic has just started doling out heat when it feels like it regardless of where I set the dial. It seem that when I am accelerating or applying gas, heat is available but when I am stopped at a light or coasting downhill, cold air is all that is available. Is this a thermostat issue or something more dire?

Overheating - Nissan - Sentra - Heating :: Intermittent Heat / Blowing Cold Air

A few weeks ago my car started overheating and blowing cold air while I was on the highway. I took it to my mechanic and he found that the radiator was leaking. Two weeks later the car was overheating and the heater was blowing cold air when I was on the highway. I had it towed to the same mechanic and the car wouldn't overheat nor would it blow cold air. He drove it all around and on the highway but couldn't get the problems I was having to occur. Now I have intermittent heat. Sometimes I will start the car and it will take 20+ minutes for the heat to blow warm air. Other times the heat works fine for a while and then starts blowing cold air. Usually when it starts blowing cold air I begin to smell a sweet odor, possibly coolant. It hasn't overheated again, but I have stayed off the highway.

I just had the thermostat changed, and the upper radiator hose warms up quickly. When the heater is blowing cold air, one or both of the hoses connecting to the heater core do not warm up. Sometimes it's both hoses, other times the hose going in is hot but the other hose is cool. My mechanic seems to think that the head gasket is leaking air into the system, and that the air is preventing the coolant/water from being properly transported throughout the car. He did a pressure test to see if it was the head gasket when I brought the car in but it wasn't conclusive. Does it sound like a head gasket leak, or could it be a blocked heater core, or a weak water pump? So far I haven't noticed any coolant leaks, but I could be missing something.

Saab - Heating - 9-5 :: Blend Door Motor Not Opening To Allow System To Switch From Air To Heat

I have a SAAB 2000 95, and the heat isn't working. I was told by a local shop that the blend door motor isn't opening to allow the system to switch from air to heat. He said that the heating system was working, but that the hot air can't exit the dash. He said it would have to be repaired at a dealership.
