Golf IV / Jetta IV :: Heat Blows Warm At Best - A/C Isn't All That Cold
Heat blows warm at best and A/C isn't all that cold. I want to believe its a blend door issue and dive into it this weekend and fix it but there isn't a single piece of foam coming out of any of the vents. Of all the systems on the car, HVAC isn't my cup of tea I don't know anything about it. What else could be the problem? I can live without A/C but the heat things must be fixed.

Just picked up an 87 150 and have found the following few problems. (Chilton no longer has a "troubleshooting" section...taking that POS back). Anyway here we go... No heat. AC blows cold, but there's no heat. Possible problems and fixes?
View 9 RepliesFord A/C :: Heat Blows Cold Air
I'm having with my truck. During a drive cross country my heat started to go from hot to mildly warm to cold in probably 5 hours. After stopping I checked my coolant level and it was empty. I do have a leaky head gasket and have driven about 18 hours so I'm guessing that's where it went. I could not find a leak anywhere. I filled it back up and left the cap off the reservoir to let any air work it's way out. My heat still blows cold as ice but if I shut off the heat completely and wait ten seconds then turn it back on it will blow warm air for maybe two seconds. What this could be?
View 3 RepliesSaab - 9.3 :: 2005 - No Heat / Fan Blows But Cold Air
My daughter has complained about periods of no heat- fan blows but cold air. Next time the heater works fine. She is keeping coolant level up but does need to add a bit (pint or so) say every other month. Last week during the Chicago snow storm she called and told me the heater (which had been working) blew a bunch of "smoke" into the car and onto the windshield and windows which then froze solid. I assume the smoke meant steam and she did say it had a sweet smell when I asked her.
Car was towed to a SAAB dealer who ran the car for a couple hours and found no issue and then drove the car for a period with no issue. I had my local mechanic also check it in the past for no heat and it also worked fine then. Only thing I can think of is that there might be a small/intermittent leak in the head gasket with an exhaust bubble forced into the cooling system? That does not explain the steam in the passenger compartment though. Could it?
Ford Excursion :: No Cold Air Blows Only Heat
I have a 00 Ford Excursion and only heat blows out of the front vents, the temp control doesn't work at all! The back has it's own controls and will come out cold (not a/c just the outside air) when the front is on (blasting heat). What this could be?
View 10 RepliesLS / MKZ :: 2002 - No Heat / AC Blows Cold At Any Temp Settings
I have no heat in the LS at no settings. The AC runs good but does not seem to be regulated as it blows cold at any temp setting. The fan responds to settings but i still get no heat even with the AC turned off. I would like to find a diagram that shows the locations of the bleed valves to start a coolant air bleed.

My g/f's 98 Passat 1.8T has been pretty bad on being able to blow hot air inside, and now that its colder out its even worse.
Ever since she got the car, the coolant temp gauge is always at it's coldest, so I'm thinking its time for a greentop sensor. Her coolant right now is a lil low so, in the meantime, I'll be headed to the dealer to get both a new CTS and some G12.
Her fan does blow air, but could there be anything else wrong that would keep it from blowing hot air?
Ford - Ranger :: 1997 2.3L - Intermittent Heat / Blower Just Blows Cold Air
There used to be a audible pop in my stereo speaker when my heat would kick on. Now there is not. My heat did this last winter around the same time. I checked Fuses. The blower blows, but it just blows cold air. It could be a thermostat, or a clogged heater core. 1997 Ford Ranger 2.3L ...

I have a 2002 Dodge Durango and the rear passenger air blows cold only - was fine last winter. Neither the passenger or the driver controls will get warm air to the rear via the overhead vents. Warm air comes out under the front seats to the rear only.
View 1 RepliesFord F-150 - 1997-2003 :: No Heat / Blows Cold Air No Matter What Setting At HVAC Controller?
My brother-in-law has a 97 F-150 with 4.6L that has no heat in the cab (blows cold air no matter what setting at HVAC controller). Heater core was replaced one year ago and T-stat was replaced last night. Coolant level is full and the heater hoses are BOTH hot so I believe warm coolant is flowing through the heater core. I am thinking that the HVAC controller may be at fault or maybe the mixing door in the HVAC plenum is malfunctioning. I have 97 rangers that had a broken hinge pin for the mixing door inside the plenum (a common problem with these trucks), maybe this is the same issue (I don't know). I am taking the whole dash out to see what the trouble is.

My 2009 silverado ltz is haveing heating issues. when you first start truck all work fine. After a couple min the drivers side vents loose heat and blows cold air. the heat on the pass side works fine. then the vent will change to defrost even though the display still shows its on vent. the only way to get it back is to mess with the vent control. then it will last about a min then back to defrost. at this point i just turn it off. I have already replaced the control panel to no avail ...

I've read that this is a somewhat common problem but can't find the part number to what I need. My heat stopped working and won't change blowing any temp only blows slightly chilled air. I found that its suppose to be a part in the dash that controls this thru the climatronic head unit some lever that isn't getting pushed over correctly dew to a worn out part. What part I need to get my heat back working.
View 4 RepliesSilverado :: Cold Always No Matter Where The Temperature Selector Knob Turned - No Heat
I have a 2010 chevy silverado. No matter where I turn the blower selector switch, it always comes out of the vents. Also no matter where I turn the temperature selector knob, it's always cold. It's a company truck that I can't get fixed soon because of downtime and I'm not supposed to take it to get fixed on my own time. It was 37 degrees this morning on my drive into work.
View 4 RepliesFord Super Duty (1999-2016) :: Temp Gauge Spiked - Cold Air Blown When Turned Heat On
I have been having a problem with my 2002 F250 Super Duty 4x4. It started about 2 months ago. I was in traffic (truck hadn't even been on for 15 minutes). The temp gauge spiked, so I pulled over and turned the truck off. I turned the ignition on and the gauge was normal so I started it and all was fine.
Fast forward a little and every so often about every 3 weeks it would overflow (coolant) but not get to the point that it would overheat. I changed the thermostat and all seemed good to go. Fast forward to yesterday morning. Got in the truck and left to go hunting, and I didn't even make it 10 minutes down the road when I turned the heat on and it blew cold.
I started to see the gauge creep up so I pulled over and shut it down. Upper hose was cold, lower is cold and both heater hoses are cold. After some time of waiting, I started it but the gauge kept creeping up and no heat, so I kept shutting it down. After about 5x of this, the heat worked and the upper hose got hot and all was right with the world. SO I drove it home. Coolant is new, flushed about a month ago and was running great since then. Thermostat is new. Do I have a blockage somewhere? Water pump bad?

View 2 RepliesGolf/GTI VII :: Driver Side Air Vents Only Blows Cold Air?
2015 GTI autobahn w/pp. Couple of days ago i started to notice that the driver side air vents only blows out cold air even when the car is warmed up.
So I decided to try turning up the temp to hi for both sides, and i notice passenger side is blowing hot air like it supposed to while driver side is not. (this happens with and w/o AC).
This happens maybe 2/3 times i start the car, so I looked up online and seem to only find people complaint about air staying hot when temp set to low w/o AC....
Golf IV / Jetta IV :: Engine Temperature Rises When Heat Is Turned Off / Hard Pull
I have a 1.8T with 152kmiles
Recently, both the coolant reservoir 'Y' connector and the driver side coolant flange cracked and I was shooting G12 all over the engine. I've replaced both of the parts and the coolant temp sensor with a "green top". Reservoir was refilled with the proper ratio of G12 to distilled water, ran for a bit and topped off accordingly.
This morning I started my drive to work and the engine temp was at 0 for a minute or so and started to climb slowly to 190. It stayed at 190 until I took the exit to the highway and the temp slowly started to rise while I was at 60mph. I immediately turned around and went back home with the heat cranked to high. With the heat on, the engine temp would slowly go down but then rise again if I, A. turned the heat off or B. made a hard pull up to ~55+mph.
I popped the hood and the coolant was not boiling and I couldn't see/smell/hear any leak. could this be the thermostat or is this a water pump issue? I plan on taking the thermostat off and checking the pump empellars for any shards. I'm not sure but I do believe the water pump was replaced by my parents while I was on deployment.
