Question about 2003 Chrysler Sebring

2 Answers

No heat My heat will not work, just blows cold air, when the car is at idle. I have to reach 2000 rpm to start getting any heat and then when the rpm drops so does the heat. What is causing this?

I am having the same concern. What I've found was a leak in the air bleed manifold(water outlet housing) or whatever people want to call it. It is located just to the left of the intake manifold. The leak allows air to get in the system. When air is in the system the coolant is not getting to the temp sensor when at idle thus blowing cold air. If there are no leaks and the coolant level is OK then the system can be bled with the bleed valve on the housing. Of course there could be other reasons for the leak besides the housing.

I would say the heater tap is not functioning correctly they run on vacuume so it could be anything from the heater tap itself is faulty or there is a hole in one of the vacuum hoses that run the climate controll system for the car, thats why extra revs more vacuum means you get some response from the heat. best bet, vacuum test to determine if that could be the problem, if vacuum is fine begin tracking down the heater tap, im in australia so am not familiar with the make and model you drive but they are in one of two places on the heater hose leading from the engine to the fire wall or in the blower fan heater box assembly. hope i have helped.

There is no heat from heater at engine idle speed.


I have to believe that your thermostat is still sticking....replace it and you problem should go away. Relatively inexpensive fix.

Ac blows cold air for about 15 minutes then starts blowing warm air then starts blowing cold air again freon is full


Freon is not full. If it goes back and fourth it is pumping then reaching a low pressure on the low side below 35 psi. Pressure while car is off should be pegged. Check at idle should be around 50 psi and 35 psi at 2000 rpms.

Good luck. If problem persists evac system replace dryer and recharge.

2001 Dodge Caravan heater blows cold air when stopped


Have you checked the coolant level? What you describe is exactly what happens if the coolant level is low. When stopped at idle, hot coolant is not circulating through the heater core, so no heat. As the engine increases in rpm's when you pull away from the light, the water pump is spinning quicker, and some coolant is making it to the heater core. So check the level, and if it is low, keep an eye on it to see if it drops again. That of course indicates a leak somewhere. Get it fixed, as overheating the engine leads to costly repairs and worse case a new engine. Let me know how you make out with this.

Heat blows cold when car is idling


You have an air pocket in the cooling system. To bled it out you will have to park vehicle on an incline or jack up the front end untill the radiator cap is higher than the heater core. The remove radiator cap and run engine until warm then hold rpm to about 1200 rpm's and top off coolant level until you have no more bubbles.

Heaters randomly blow cold, idle jump


Make sure your anti-freeze is full in the radiator.. If it is low, the heater is the first to go, but you wont see signs of overheating.. This I believe is also contributing to your idle fluctuation.

No Heat in 99 Taurus


Just finished fixing my daughters 1999 taurus heat. It would blow warm only when running down the road. At idle it blew cold. I started with replacing thermostat, and water pump because they are the easier fix. Still did not help. Then I replaced the heater core. A daunting job but not that hard to move the dash slighly out of the way to replace. There is a good write up at tarusclub.com. After that, heat was better but at idle, it would still blow cool sometimes. Researched and found answer. Park car on the steepest hill you can find with front of car up. Start car and take off reservoir cap. Let car warm up and keep rpms about 1500. After a while the fluid will come running out of the car and all over the place but it will bring air bubbles with it. Reduce rpm, add more fluid and repeat about 3 times. It will make a mess but after that, the heater works perfectly. We get heat long before the temp gage indicates any and it never blows cold unless you lower the temp.
