Santa FE SM (2001-06) :: 2003 - Heater Just Quit Working While Driving On Highway
Dec 21, 2016
Today, while driving on the highway, my heater just quit working. My car is equipped with the automatic climate controls and so I switched it to manual mode to see if the heat would come back. The heat does not seem to be mixing at all with the air.
One weird thing is that if I set the temperature to 90 degrees then the A/C mode will turn off and blow pure hot air. However, if I go to 89 degrees then the heat will stop and the A/C will turn on again. Turning off the A/C manually does not bring the heat back.
What could be wrong? I might just try unplugging and reconnecting the controls since I was messing with the radio a couple of days ago.

My daughter was driving our 3.5L Santa Fe on the highway when it decelerated. Stepping on gas and no acceleration. She said she got a CEL and oil light. She was able to pull over to the side of highway and turned ignition off and on and she was able to drive off the highway and called me. She was about 120 miles from home. She said the cel light and check oil light were now off and I had here check the oil and it was at full.
I had her drive in the right hand lane without going over 60 and she made it home no problem. I took it out for a drive and no issues. Do you think this is a crankshaft position sensor problem?
mileage is 170k - timing belt was replaced at 130k.

2003 Santa Fe - Loss of power while driving on highway. Dropped from 60 to 15 MPH in matter of seconds. Feels like a couple of cylinders (3.5 liter) are not working.

I have a 2000 F-150 and my lights to my gauges and heater controls quit working. I checked all the fuses inside and under the hood. All good. I swapped a few relays around and no luck. I tried replacing the headlight switch and that did not work. I checked power to the gauges from the headlight switch and there is no power, I then ran a hot wire to the wire that powers the gauge lamps and they do light up, so it is not a bulb issue. I assume I am not getting power, but do not know where else to look?

Driving down the road, no warning lights on, everything working fine, no stalling or any indication of a problem, car just shuts off. I think hmmm, put it in neutral and try to start, nothing, notta, zip ... engine not even attempting to turn over. Removed the battery took it to store had it checked twice shows to be good 100%.

I was recently on a road trip, using my cruise control extensively (like usual) when it just quit working. I tried to reset to a lower speed, but it would rev itself back up to the original speed. I turned off the cruise control, drove a mile or so and turned it back on. The cruise dash light came on, but the right control buttons no longer worked. No check engine light. It's never worked since.
My local tire shop checked codes and found the tcm not communicating with the mod (cruise module?). I'm looking to take it to the dealer, but I'd like to be better informed with what I may be dealing with before I get there.

I have a 2005 Santa Fe, and both power mirrors quit working at the same time. I plugged in a different switch, and still nothing. I checked the 10 amp fuse under the dash and that was good (is there a different one). The locks still work though.

It was blowing cold and stopped. Minutes later it started again and then stopped. This went on for a week and then stopped altogether. Car has 190,000 miles. Is it compressor, clutch or relay....

My heater works when engine on tickover then stops working after a mile or so driving. I have taken heater hoses off and it does not seem blocked and have replaced the engine thermostat. Now what can I do??

I inherited this car from my parents a couple years ago with about 80,000 miles. It ran great for awhile, then the air conditioner and the gauges would quit working while driving. After a few minutes they would resume working and everything would go back to normal. Now it will start sometimes and will not start at other times. I have replaced the battery two times and it seemed to work for a short period. I have had several mechanics look at it. After checking the code and replacing a fuse or sensor and replacing the ignition switch the car is still doing the same thing and no one has a clue what is going on. It seems to me that it may happen more often when going over a bump. What could be causing this?

I currently own a 2003 Hyundai Santa Fe with 135,000K miles on it, and have had continual problems with the A/C not blowing cold over the last year or so.
A year ago, took it to what I thought was a reputable mechanic (not a dealer) who diagnosed the problem as a "bad" master circuit board. Thing ran fine for about 6 months, then started to intermittently blow warm air, until it finally quit blowing cold.
Finally broke down and took it to the dealer hoping they would be able to fix the problem. They charged me $110 and told me the refrigerant was low so they topped it off. 6 weeks later, once again not blowing cold, took it back. They said this time they found a "leak" in the refrigerant hose, replaced the hose, topped off the refrigerant, and sent me on my way (free of charge, of course, since they should have fixed it the first time).
Well...6 weeks later and once again, not blowing cold, so back to the dealer I go. Once again, they said the hose was "leaking" and they did the dye test (shouldn't they have done this the first time?) and replaced the hose, and the refrigerant. Good for another 6 weeks, then once again, not blowing cold.

We have an '03 Santa Fe (2.4L). We are the original owners.
About 18 months ago, one of our Ignition Coils cracked and caused a misfire when then engine was under load. I replaced the coil, wires, and plugs myself at that time.
Since that time, we have experienced intermittent engine jerking while at highway speeds. There does not seem to be any pattern, and it does not happen every time we drive it.
I took it to the dealer who diagnosed a valve cover leak. They replaced the gasket, one ignition coil, wires and plugs. The problem still happened intermittently after that. I brought it back to the dealer, who diagnosed a valve guide/seat leak. Oil is getting into the cylinder and fouling the plug they say.
I could not afford the fix (and was very dissatisfied by the service I received) so the dealer recommended to change the plugs every 3 - 5K miles to get me through. I was told this on 03/31/09 (125695 miles). I replaced the plugs, wires, and BOTH coils again at that time.
Last week @ 130K miles the engine jerked again. I replaced all four plugs again Sunday morning, but the ones that I pulled were NOT look oil fouled. I showed them to a mechanic friend and the guy at the auto parts store. Both agreed that the spark plugs looked almost new. Sunday evening, while driving on the freeway, the car jerked again!
Since this happened again SO soon after changing the plugs, I really have a hard time believing the valve guide diagnosis. Some possibilities I have seen/heard:
- Crank position sensor or camshaft sensor (This was replaced at 78K miles along with the all of the belts)
- Clogged fuel filter
- Bad O2 sensor
- Vacuum leak from the hose that is between the throttle body and the engine casing
- The dealer's valve seat suggestion

2010 full load Tiguan- perfect this a.m., but wife went to drive home & no blower fan. The dial lights up and moves as dial turned, but no fan at all.
Checked the fuses under dash, nothing burnt out. What am I missing??

I have a 2007 Saturn Relay with heated seats. One of the seat heaters has quit working and now the other one gets super hot after it is turned on for a while. What is causing the seat to get super hot? I don't want to burn up anything.

I have a 2001 F150, 2WD, 5.4L. Neither the heat nor the air conditioning works. The blower works fine on all settings, and the air blows out of the correct ducts in accordance with the switch settings. The problem is the heat does not blow hot, and the AC does not blow cold. Everything is just the temperature of outside air.
If I jumper power to the compressor at the relay socket in the fuse box, I can make the compressor run and it provides cold air. The relay does not seem to be the issue because replacing the relay does not work. The heater core is hooked up, just no hot air.
I was thinking maybe the problem is in the temperature level switch in the dash panel. Does that sound like the best possibility? Do you think these problems are connected, or am I looking at two different issues.

My heater/AC blower quit working. Does not work with either heat or AC. I suspect a blown fuse but cannot find one for the blower.

I had to replace the vacuum control for the heater in the dash panel. The fan worked good on all 4 speed settings but only in the defrost position due to the damaged control valve. The control valve works all position for the heater positions now. There is power at both sides of the heater fuse under the dash but no blower function. Is there a fuseable link elsewhere in the system to check. Is the fan motor only accessible to test by accessing the heater/AC under the dash on the passenger side. 1973 Crew Cab....

On my '03 Santa Fe 2.7, this has happened twice, with 500 or so uneventful miles in between. At highway speed, it just all of a sudden loses power and will only go about 50 mph with accelerator to the floor. When you stop & put in neutral, it only revs to about 3000 rpm, with pedal to the floor -yet idles fine. Then when you shut it down, wait a few minutes & start it back up, it's fine. Is this a fuel problem or what?

Driving down the highway today, my car just all of a sudden quit. I had it towed home, and checked the spark and fuel pump. It turns over fine, there's plenty of spark, and the fuel pump works great, but I don't think fuel is getting all the way to the engine. Could the fuel line be blocked or something? Maybe the injectors?
