Was just on a trip (about 200 miles or so each way) and the AC worked just fine.
Car has sat for a few days unused.....when I used it to day, the AC blows warm...doesnt cool at all.
I hooked up a gauge to the low pressure side and the pressure reads very high (in the red zone of the gauge).....
Cant tell if the compressor is kicking on or not when the car is running...
Car is 600 miles out of warranty (of course).
My 2006 Sonata GLS 3.3 A/C started blowing warm, so I checked all the fuses and they were good. Swapped the relays and still nothing so I check the wire to the compressor and it was reading 14v. This would lead me to believe the a/c clutch is bad, I didn't want to replace just the clutch incase my compressor craps out on me later on so I'm just replacing the whole thing now. My questions is how much oil does a new compressor need?
View 3 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..
Having problems with the A/C on F150 2006 or newer. It blows warm air while idling. I have taken mine to 2 different dealerships had Ford engineers down and no one can seem to find the problem. I love Ford vehicles but I can't handle this in the these hot summers.
View 10 RepliesTwo weeks ago A/C was slow to cool down on and blowing warm air for several minutes; works fine since then. One week ago, check engine light came on. At the dealership now, they say it the check engine light is for the clutch heater and this would also relate to problem with a/c not cooling properly. Waiting to hear what repairs will cost. Is this OK to continue driving? What exactly is going on? Does this part need to be replaced? Should we just tape over the icon on the instrument panel to avoid looking at the pesky light?
View 1 RepliesI have a 2007 Sonata and It recently lt began to blow hot air out of one side and freezing cold out the other side. Took it to the dealer and the technician said he didn't know what was wrong but recommended that the system be evacuated and refilled at a cost of 281.00. Actually, what he said is that the compressor is either overfilled or underfilled.
View 16 RepliesI'm working on 07sonata 2.4. The cooling fan is always on when key is on. I used to be a hyundai tech and remembered seeing something about the engine room fuse box and I have access to wiring diagrams. So in essence you go to connector jc01 pin 2 pink and connector je01 pin 25 pink. Cut the wires and connect them together bypassing the fusebox all together. But that didn't work this time. One thing I discovered is that if I touch my power probe to the heatsink of the fan control module I have battery voltage available. I first discovered this because I was removing said module and my 10mm touched it when it slipped a touch.
Is this 'hot' heatsink evidence of a shorted module? No codes in system. Ect tests good when hot and cold. A/c is not commanded on. Being that I used to be a tech for Hyundai I also know the engine fuse box can be touchy as well...
I have a 2008 Azera, my A/C is not working properly, when I turn it on the drivers side is COOL, the passenger side warm air is coming out.
View 1 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).
I notice a high pitch squeal when I turn off the car ignition and is synced with the slowing of the engine cooling fan. I don't notice any significant engine noise while the car is fully running in idle. Does this indicate that bearings are going bad in the electric engine fan assembly? If so, would the noise alone be justification for getting a warranty replacement by the dealer or would they need a total fan failure in order to get it replaced under warranty at no cost. If not, think its worthwhile to replace the fan module myself to avoid imminent failure?
2009 Sonata GLS (NF) 50k Mileage
My '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!
I've recently purchased a 2007 Prius and I just noticed few days go that A/C blows warm air (weather was fair when I bought it and I can't remember if it really worked or not then) and middle vents do not blow any air. I'm not sure if two problems are connected but I do want to get both fixed without spending $$$ at the dealership. Where can I start?
View 5 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. ...
View 6 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 RepliesI've got a 2007 Sonata that has started blowing HOT air. It's like the compressor isn't on. In looking for the issue, I looked for blown fuses first because I find it hard to believe that the AC would work fine and then stop working minutes later. Sure enough, I found a blown A CON fuse in the fuse box under the hood. No problem right? Just replace it and everything will be A-OK. WRONG. Every time I replace the fuse and test the AC it blows. I'm thinking maybe something with the relay?
View 11 RepliesBasically when I have it cranked on high (level 4) it feels like its blowing on level 2. some times when I start the car it doesn't even turn on. I have to tap or hit under the glove box for it to start. Is it wiring or could it be AC Blower fan or something else.
View 3 RepliesSuddenly my 2007 Sonata Limited trunk and gas lid fuse keeps blowing.
I'm not an electrical guy so I don't know how to check with a meter, I oiled the latches. My car was rear ended near the tank lid/bumper area a few years ago, but everything worked fine til recently.
I can replace the fuse, but after a few uses it will blow, sometimes it will blow without being used. I can't tell if it's the trunk or gas lid causing the problem because nothing will happen immediately, Basically I am only finding out my fuse blew when I need to use it.
Where I could look to inspect the wiring for kinks or it's connection run?
I tried installing my new DDMTuning 35W 6000K HID headlights with relay harness. No issues until I went to turn the car on and actually power them up. Neither side would work. I checked my power connection, ground, in-line fuse, swapped out the relay, tried without the harness, and nothing worked. I tried putting the stock bulbs back in and I found out they wouldn't turn on either.
I found the issue to be a blown 20 amp fuse in slot 23 (see pic). I replaced it and tried to turn the car on with the HIDs and it blew again. I hooked the stock lights back up and they seem to work fine now with another new fuse. The fuse description says H/LP LO and HID LO LH. Why this fuse is blowing. I am wondering if I just need a higher amperage fuse because of the HID power (in line for harness is 30 amp) or if something else is the culprit. I'm stumped.
I got in my 2009 Sonata this morning, started it and turned on the headlights. The headlights turned on momentarily and then turned off. The 20 amp headlight fuse blew. I cleaned the battery ground on the fender and the battery terminals. I also cleaned the connection between the battery terminal connector and the negative cable. I put everything back together and installed a new 20 amp fuse. I turned the lights on. They lit momentarily and then, predictably, blew the fuse again. Curiously enough, the "passing lights",which are just the high beams on another position on the headlight switch, still work.
View 2 RepliesA/C on my 2006 V6 3,3L Sonata just stopped working properly today when driving away from a supermarket, it blows only very hot air regardless of the temperature you choose on the display. It worked fine while driving to the supermarket and nothing remarkable happened to the car while I was shopping. All lights on A/C display, fan speed and everything else works fine, it just doesn't react to the temperature button at all.
I already checked the 10A A/C fuse under the bonnet, it's fine. There is an A/C relay in fuse box that I can check tomorrow but I suspect the fault to be somewhere else.
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.
