Touareg :: 2004 - Heater Not Working?


Oct 14, 2007

The heater on my 2004 Touareg V-8 appears not to be working correctly, although the dealer has said they they "calibrated" it and that that all is well. When the ECONOMY setting is on, as I understand it, I should be receiving external air, heated/vented from the engine whenever the setting of the heater (i.e., inside) temperature is higher than the outside temperature. However, even when there is a difference of 10 or more degrees, I cannot feel any heat coming from the vents.

Tonight, it was around 58 according to the thermometer on the dashboard, and I had the heater set to 70 -- NO HEAT. It required setting it to 74 before I felt anything. When the Economy setting is off -- when the heat is run through the compressor -- I get somewhat better heat, but the principal difference is that it happens more quickly. It still requires a spread of MORE than 10 degrees to get ANY heat. This happens in the winter and on cool nights during other seasons. Why should I have to have the heater dials cranked up to 74 - 78 top get normal heat?

The heater/ac blower stopped working on my 2004 Lexus GX470. All the lights and display work but the fan doesn't work on any speed. I replaced the relay in the fuse box under the hood but no luck. I removed the blower and it works when I hot wire it to the battery. I checked the voltage coming into the blower and its at 13.5V, same as coming off the battery but it doesn't turn the fan.

Nissan - Sentra :: 2004 - Heater Occasionally Stops Working

Our Nissan Sentra 2004 heater occasionally stops working, usually when its very cold of course. Usually, the heater starts working fairly quickly but then starts blowing cold air. If you move the vent dial to different positions something changes and the heat starts working again. A mechanic says that something in the heating vents has probably come lose and to find it quite abit of the engine parts will need to be removed resulting in a big bill.

Touareg :: 2004 - Keyless Entry Quit Working

My wife told me the other day her keyless entry quit working on our 04 touareg. The remotes still work but only at close range (I just read the sticky about this) but when you grab the handle and the door is locked it doesn't unlock any more. Also when the car is unlocked and you shut the door and press the black button on the handle the car does not lock anymore. I really liked that feature and had just showed it to her and then she tells me it quit working. I would rather not take it to the dealer if I can fix it myself. I looked in the settings and didn't see anything ...

Touareg :: 2004 V8 - Driver Side Xenon Low Beam Flickered Rapidly And Then Quit Working

Troubleshooting a headlight problem on a 2004 V8 Touareg. Driver's side xenon low beam flickered rapidly and then quit working. I replaced xenon bulb with OEM part, still not working. Swapped in known good bulb from passenger's side, still not working. Took to dealership, who said it needed new ballast, which dealer would be happy to install for a mere $900 in parts and labor. Declined dealer's offer, ordered new replacement OEM ballast (from Chrysler dealer for several hundred less than VW), installed new ballast, still not working. Cleared all fault codes using VAG-COM, still not working. Swapped in known good ballast from passenger's side headlight, still not working. Auto-leveling is still working in both lights. So...not the bulb, not the ballast. Wiring harness, perhaps?

Intrepid :: Heater Seems Not Working

I'm working on a 1994 Dodge Intrepid with a 3.3L engine. The heater isn't working very well at all. I have run water straight through the heater core with a garden hose and it doesn't seem to be clogged up at all. I have also taken the blend air door actuator off and made sure the blend door was set on heat. Also, when the car is warmed up, I can pinch all of the heater hoses off by hand, and I don't feel like there is much, if any coolant flowing through them. The car isn't overheating or anything, so I'm wondering if the water pump could be working but just not pushing enough water through the system to run the heat?

Phaeton :: Heater Stopped Working - How To Get It Out

So my aux heater stopped working. It may just be a failed glowplug as per the error code but as there is significant corrosion around the controller I thought it best to get hold of a second hand unit, which leads to a couple of questions.

1. Can the glow plug be changed with the heater in situ?

2. What needs to be removed to get the heater out? Is it a big job?

Even my mech says it's easily the most complex car he's worked on, and he's had Ferraris/Porsches etc in before!

Prius C :: Heater Blower Not Working When Cold Outside

I have a 2012 C 3, with 27K miles. This morning on the way to the store i turned on the heater and the fan turned on and after like 2 mins the blower stop working. All the lights are on, but nothing comes out of the vents under any circumstances. I tried taking of the ECO mode, I tried turning the car on and off. still nothing.

If I bring it to the dealer will they fix it under warranty? Could it be a bad fuse? where is the fuse box? What could it be, its freezing outside and I need heat for the kids in the car.

Passat (B5) :: Heater Stop Working After Driving A Bit

Last week, temps. dropped so tried heat on `02 GLX few months out of warranty. took to dealer (concerned with locals and the VW climate control), dealer said clogged heater core, they asked if it had overheated (no), $1500

VW kicked in $500. nice weather when I picked it up, next door cold, turned on heat, but there was none. took it back to dealer, they said it was an air bubble and said they "bled" the system, and viola, had heat in 1/2 hour. Worked fine for couple of hours. Couple of hours later, again no heat.

Any clue? Did the dealer know what they're doing? Did I get ripped? Can others work on the VW climate control or is it related to the actual mechanics of the heater?

Elantra XD (2001-06) :: Heater / AC Blower Not Working

I have a 2004 Elantra. The blower for heat/ac not working. I did all of this:

Checked interior fuses, all OK.
Checked 30 amp fuse in engine compartment, put a new one in.
Pulled blower motor out and tested with a 12V power supply: worked fine.
Replaced Blower Relay
Replaced Blower Resistor
all of this and still no blower.

The heater control panel on the dash has 3 knobs. When I turn the first to AC...the light comes on and I hear the AC kick in. 2nd knob is blower fan...nothing on any setting. 3rd knob...hot and cold...not sure since no blower.

I am lost at what to do next.
