Car does not heat up despite debater being on and letting ca run for 15 minutes

On cold mornings I got to turn my car on to let it warm up. I turn on heat and set up 80 degrees and have defroster on. 15 minutes later when I go to get in the car the window has not defrosted and it is still cold in the car. It also smells likes gas in my car. However, once I start driving the car in about 10 minutes the heat , etc will begin to work. what is wrong and will this be an expensive fix?

Th e car is over 8 yrs.old and how many miles? The coolant been changed out after 4 or 5 yrs. of say 15,000 mi. per yr.?
What I'm getting at is your thermostat could be only partially doing its job or corroson or build-up (scummy deposits)could be interfering with your electrical signals from sensors.
Drain it,flush it and replace thermostat,then refill it. don-ohio (:^)

There are several things which come to mind. You have 2 complaints. A gas smell and a cold blooded vehicle.

Starting with the temperature problem. My initial concern is whether the thermostat is weak, but also that the automatic controls may be inoperable and working against you. The car is suppose to go into a temporary "cold start routine" which increases the RPM and makes the fuel rich. (This could contribute to the gas smell)

After the Temperature sensor and O2 sensors warm up, the idle is suppose to drop and the fuel mix should lean out. If the engine remains at high idle, the water pump will work faster with the engine spinning faster. Sometimes there is not a direct 1 to 1 ratio between the heat generated by the motor and the RPM versus the cooling produced. An idling engine may warm up faster than an engine running at higher RPM.

Another problem may be the Defroster setting. There are Thermal switches which are suppose to cut off the Electric Radiator cooling fans. When the Defroster is activated, some cars are built to spin the A/C compressor in the Winter. But the Electric Radiator cooling fans may also switch on as part of the A/C system. This would super cool the radiator at a time when you least want it. Check to see if the cooling fans are activating when the Defroster is turned on.

There can be 2 Temperature switches in your car. One would send the signal to kick out the "cold start routine" and the other would work the guages or indicator lights.

The O2 sensors can have heaters in them or they can just be slow. If you leave the engine idling like you do, they could foul out and be sluggish to warm up.

If running the Temperature at 80 degrees causes an additional 5 minutes of warm-up time, you may be better off setting it for say 72 and having it work sooner.

The thermal sensors are not that expensive. Work on a cold engine when changing them. Note what I said about your rich fuel mix contributing to the smell.

Please rate my info.

Replace the thermostat, if that does not cure the issue you have a slight head gasket leak. I am a retired Ford dealer tech and this is what I have found causes this issue.

there is a blend door and a selector door in the HVAC system. These are run by vacuum or servo motors. Sounds like this little motor is your problem. Hope this helps you.

SOURCE: while driving my 95 explorer i noticed the heater

no heat is probably low coolant or bad thermostat,although you have fog and smell ! the heating and cooling systems are closed systems the only way the windows fog is the coolant is hot and steams inside the car due to some leak inside the heater core box. as well as the smell being present. Now it is possible that a little leak has occured where the coolant supply or return line connects to the heater core and is running into the car which is running onto the core and creating steam and smell. hopefully it is a easy clamp tighten fix for you.

In the morning when 1st starting the car, the climate control does not work


If the climate control is on "auto" there is a delay before starting. For 15 minutes it is either freezing cold outside or needs repair. Depending where you live. Well anyway a way around the delay is to go to a manual setting and the system should start blowing right away.

Of course if it hasn't warmed up yet the air will be cold!!

Track the temperature gauge on the dash. As the temperature lift's off and approaches normal range heat should be coming from the vents,

New cars that are super efficient are very slow to heat up. The old gas gushers had plenty of heat to spare

So if you think it is cold where you live heck out the videos,

My heater blows hot for a couple minutes then turns cold. After turning it off for a few minutes and back on, it blows hot then goes cold again.


LET YOUR CAR WARM UP FIRST!! or you risk the chance of over heating and casuing engine damage. start your car let it warm up for 5 to ten minutes and then try the heat. also when you start you should NEVER have heat on right away. the heat that you feel comes from the engine. and if the engine is cold and you are trying to heat it up it will put stress on the engine and over heat. ALL cars have to wait for their heat. that's why you see peoples car running in the morning with no one in it. so when they do get in it they have heat. heat will not work until the engine is warm.

Chevy 2005 tahoe z71 blows cold air in back but hot air in front


Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).

The fix:
Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process.
In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.

If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.

Good luck.

When it is cold out and I start the car in the morning and put the car into drive there is a hesitation for up to 5 or six seconds


In really cold parts of the country that is pretty normal. Your automatic transmission fluid needs a few seconds to expand and build pressure. Let the car warm up for a minute or so on those really cold mornings.

My 1996 jeep grand cherokee is blowing cold air for the first 30 minutes of my ride home (20-degree weather), then warms up slightly but never gets hot -- i'm guessing heater core (it has 200k+ miles)


It is most likely a thermostat. As your car gets older the thermostat begins to lose its spring like properties and stays open all the time causing your car to never warm up.

If you can't tackle right away, start your car in the morning and let it run for about 15 minutes to warm up. Be sure to turn the heat on full blast and recirculate the air.
