The heater in my '07 Sonata (V6) does not seem to do too much - the air gets warm, but not hot - even at full blast. (A real problem here in Wisconsin when the outside temp gets below zero). Temperature gauge always reads below the midpoint on the gauge. My hunch is I need to install a hotter thermostat.
View 5 RepliesI have a 2007 Sonata 2.0 crdi which is poorly. The heater stopped blowing out hot air on Saturday. The heater is only blowing slightly warm air. The passenger side seems to be slightly warmer. I have looked at the side of the heater matrix whilst rotating the temp control on the passenger side and this moves the plastic adjuster on the matrix freely. When I turn the fan speed controller then the adjustment on the drivers side on the matrix moves. Both of these move freely.
View 6 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 RepliesSo the story goes that one day my 2013 RX350 stop blowing heat from the air vent. I took my car in the dealer to have to take a look. First of all, it took them a WHOLE week to diagnosis the problem, second of all, a consultant told me that he FOUND a pen inside the heater box that caused the gear shaft to break, which is used to control the heater doors...
What is he talking about? More importantly, he's saying I "accidentally dropped a pen" from the passenger side compartment storage and it somehow caused the heater door broke?
Our 2005 Sonata GLS with 100,000 miles has a digitally controlled system for the heater & A/C. For more than 2 years the only way to get heat was to raise the temperature up into the 85 - 90 degree range. Now we must put it all the way up to 90. When we do, the heat is extreme.
View 1 RepliesI bought a white 2015 Sonata GLS with 55000 kms on it. Car works fine but really great on gas in city with AC ( 11-12 liters/100 kms ).
And my main problem is my AC/heater vents. Its nice cool day out and I wanna roll my windows up and use outdoor air (with AC off and heating knob on cool - Blue side) but still blow warmer air (the more I turn the temp knob to less cool side more warm air comes out). I went to dealership and complaint about it but they said can't duplicate problem. And I replaced cabin air filter too, but still same problem.
I don't have automatic temperature climate control option, so its all manual, red and blue setting for heat and cold. I complaint them may be my heater stuck on heating but no action taken from them..
We have a 2006 GX470, 90,000 miles no problems with car until 6 mths ago. A/C has been deteriorating since last yr. This summer charged twice lasted ok for few weeks. Problem initially was wouldn't cool when car was idling, only worked when going 50+mph. A/C charged worked better for 3 weeks, then drivers side not cooling but rest of car somewhat cool. Issue today is drivers side blowing out heat & rest of a/c vents barely cool at all. Told by Lexus need to rip out dashboard to get to compressor to check & fix leak. Last look by Lexus added 2 lbs of refrigerant 3 weeks ago & now completely not working.
View 1 RepliesI have a 2006 Toyota Camry SE with about 6,xxx miles on it. Called up the dealership I bought it from and they are going to charge me an arm n log to see what is going on.
The issue is there is no air blowing from Lo-High, all lights work except A/C, so i'm guessing its not the AC/Heat control.
This is what I've done so far in DYI:
1. replaced Blower motor Resistor.
2. Check the Fuse underneath the steering wheel. (Still Good)
this is what I'm going to do next:
1. Buy A/C relay $75+ tax (dealer)
2. Change Blower Motor $175+ tax (dealer)
Knock on wood 38,000 km and only now had my first set of real problems.
1. Seat heater on front passenger doesn't turn off
2. Brakes squealing
3. Keyless Fob really doesn't work well
I must say after my 05, this 06 is truly a blessing. I can't begin to tell you how utterly amazed I am with this vehicle on a daily basis. Why doesn't the car have any speakers in the rear window deck? Was sitting in the back seat on Valentines Day and was amazed at how weird the car sounds without speakers in the rear? Was truly amazed that my rear passengers couldn't hear how great it sounds in the front.
2007 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).
Have 06 super duty . Heater air blowing only on defrost. 4wheel drive. Is this a vacuum problem or some type of sensor or control problem?
View 2 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 am recently getting no AC just warm/hot air. I have yet to pressure check the system but i believe the compressor still turns. But I did notice throughout this the vents are only giving about 60% force on heat and AC as they used to. The blower motor spins although, cleaned the cabin air filter and one pin broke when putting it back. the blower motor spins louder on the "4" setting. I am guessing this is related to no A/C since it happened the same time and i don't think that low refrigerant would cause the heat system to blow less efficiently...
View 1 RepliesRandom issue that has progressively been getting worse. I'm assuming it's one of those Sonata quirks that we all deal with.
When you turn the key the starter doesn't try to crank the engine. AC stuff all works properly. I just keep turning and eventually it will turn on.

I have a 2007 Hyundai Sonata 3.3 Limited with auto air. The fan blower doesn't operate. Cannot find the relay.
View 10 RepliesI have a 2006 Sonata. The heater hasn't been working since about April. It's going to start getting cold where I live so I want to get the heater working again. My A/C works perfectly! It is only the heat that is out. What are the problems it could be having? Is this a common problem for an 06 Sonata?
View 2 RepliesMy idle seems to always be somewhat rough whenever I put the heat on in cold weather. While in drive I'll come to a red light, heat will be on and I'll stop. The. my idle will bounce down then back up. I shut heat off to test and it only does it while heats on.
View 5 RepliesMy radio never turns on with the car right away. The only way it turns on is when i crank my heat on for about 3-5 minutes. Then it powers on. Fuses seem ok. The service center didn't know what could cause this...
View 3 RepliesI have a 3.3 limited ed 09 sonata that I soo enjoy driving. However, two weeks ago the AC stopped blowing completely. It's a fully automatic unit and no air movement in any position at any temp. The compressor is coming on as I can hear it and driving on interstate I can feel the slightest bit of cold air coming thru. I bought a new resistor that was over a hundred bucks and it did nothing. I took the blower motor out and used clip on wires str8 to the battery and it works. ...
