After changing my CD player, my heater blows out cold air (not icy cold but cold like you have put the thermostat on low heat) all the time but my temperature gauge is perfectly normal! Its right in between cold and hot.
View 3 RepliesMy heater seems to not be blowing as much hot air as it used to in my 01 Accent GS 1.6 L. The air is warm, but it is not warm like it is supposed to be. All selectors work well eg. fan speed and temp selector. Engine is running normal operating temps too. So in the end, it takes forever to get warm in the car, and to keep it nice and warm, it has be on fan speed 3. if not, the car will lose the warm air faster than it can push it out.
View 3 RepliesI took my 2000 V6 Passat into the shop because my heater vents were blowing cold. They tested the system and told me the following:
The hoses leading to the heating core are warm, but no warm air is leaving the heater core, indicating that it's plugged up with corrosion. They testing the coolant fluid and found that the incorrect coolant had been put into the system and that the fluid was carrying an electrical charge that must be corroding the aluminum portions of the system. In addition, the engine temp sensor is kaput and never goes up.
They offered a garden hose flush the heating system for a few hundred bucks, but warned that it is only 50% successful. They recommend replacing the heating core.
Heater is blowing cold air. What I have checked, coolant level, replaced water pump and thermostat, checked blend door, flushed heater core. When I checked the blend door via the heater treator method I was getting hot air coming off the core but also getting very cold air coming from the A/C evap in side the plenom box. I also pulled the fuse for the A/C clutch and I am still getting cold air. I am look at replacing the HVAC contol.
View 9 RepliesGot a bit of a problem with my car. Earlier this week, I got in and noticed there was heavy condensation on the inside of the windshield of my 2002 Chrysler Sebring convertible. The windows had been rolled up and the top up of course. I see this kind of condensation happen on the outside a lot in the mornings. You know, dew settling and all that. If I wait around until later in the day, it evaporates on its own.
Anyway, this time it was on the INSIDE. I wiped it clean easily enough and was on my way.
Today I noticed that my heater wasn't working. The temperature gauge goes up to about 1/3 of the way, so I know the car is warming up. I'm not sure if it normally goes up that high; I don't usually pay much attention to the temperature gauge.
Truck has heat when driving but when stopped blows cold air. Replaced thermostat. still blows cold when stopped.
View 5 RepliesWinter is coming and I am running into a problem, I tried to set my heat at the highest level today and was getting nothing but cold air. I get ice cold A/C, but no heat at any temperature. What could be the culprit?

View 1 RepliesChrysler Town and Country. The engine warms up just fine regardless of my speed or throttle position, but the cabin heater has started blowing cold air when I back off or sit at idle. It may be relevant that we hear a lot of gurgling in the dash soon after starting the engine.
View 5 Replies01 Jeep Grand Cherokee. I just changed the water pump and the thermostat on the Jeep but the last two days when I drove it to work, the heater was blowing cold air and the engine was getting hot, almost to the red. What do you think that I should look into about getting the problem fixed>?
View 6 RepliesJust bought a 04' F250, new head studs and gaskets. Put a tranny temp sensor in and replaced bad thermostat. My coolant res is full and temp is bout 185 (it's 10* outside). My heater is blowing out cold air, I'm assuming there's air in the system.
View 2 RepliesI have a 2004 GX470. Now that the weather has dropped I have noticed that my heater is taking a long time to warm up all it does is blow cold air out of the vent. Subsequently I have started to notice that they car will start to overheat. It will never get to the point where it will hit the red but it will go up and then come back down to mid range. There doesn't seem to be anything else wrong with the car, it idles fine, starts fine etc. Could these two issues be related?

View 18 Replies2007 GS 350 109,500 miles. My heater was blowing cold at idle and warm when driving so I took it to dealer. To my surprise, dealer says its a blown head gasket. No other symptoms. No white smoke, no smells, no warning lights on dash, and running fine. Just had VVT gear recall done last week.
Fortunately I have Lexus extended warranty good thru 125k miles and Feb 2014. I do my own maintenance (plugs, oil changes etc). Have records for all. But have not done coolant change (due at 100k).
Here's what I have. 02 X 7.3L 4x4.
Heater will work fine. Then out of nowhere just blow cold. I can turn it off then back on it'll blow hot for 1 minute or 20 minutes. Then out of nowhere blow cold again. It doesn't matter if I'm highway driving or city driving.
I'm kinda thinking it may be the door in the duct that's just closing. I real don't know.
My Ford Explorer blows warm air instead of hot air and it's getting colder and my windows get fogged up. I fixed my clicking sound behind the dash.
View 1 RepliesMy '06 GS450h has developed a fault where the heater blows cold at idle and low revs but blows warm when driving or revving the engine at a standstill. The coolant hasn't dropped at all and the car never goes above halfway on the temp gauge. Its starting to get frustrating now the cold weather has set in and temps dropping! Long journeys are ok as at high speeds it stays warm but short journeys are uncomfortable!
I just had a feel of the rad hoses and hoses that go into the matrix (engine side of bulk head) and matrix hoses feel warm (both of them), the top hose to the rad is warm but not hot and bottom hose is cold suggesting the stat hasn't opened yet. Its cold outside so getting the car up to temp is quite difficult without a long drive (rush hour at the mo).
Still I just had the car parked on the drive and cranked the heater up to max and held the accelerator for a while and super warm air blows out. The engine cuts back out as "normal operating temp" has been reached for battery mode and then the heater goes cool again! Still the bottom radiator hose is cool and top hose not massively warm. It has never overheated thus far and I drive 150miles a day back and forth to Reading from Cheltenham 4 nights a week.
Only thing I can think of is a sticky thermostat or water pump not operating sufficiently enough to circulate the water? Its getting colder and short trips where it used to blow warm air nice and quickly (within 3-5miles) are becoming unpleasant!
My 08 Azera blows cold air out the drivers side vent when everything on the right sides blows heat. If I set drivers side 88 degrees it blows some warm air. I changed the cabin filter and that did not work.
View 13 RepliesOn my way home from work I noticed that my heater was blowing cold air. then I checked my gauges and noticed that the temp gauge was moving toward hot. pulled over on side of road car died on me. Husband pulled car home replaced top water hose. Now my car will not start.
View 10 RepliesI have a 2007 Saturn Relay minivan. The front heater blows hot but starts blowing cold when you stop even for a red light but will blow hot again when you speed up and the rear heater never does blow hot, what could cause this? This vehicle has about 93,000 miles on it.
View 5 RepliesMy 00 f-150 is not blowing air through the heater I replaced heater core and the temp door I had same problem before work done I did not see an issue when apart but no vacuum or electric to test when apart. The only thing that changes when I move selector for vent floor and defrost I do get a little better flow when on vent. My feet get cold and defrost is not working well if I put hand on defrost I feel warm air but 3-4" away when on floor; I feel nothing anything at all fan seems fine.
