Ford A/C :: No Heat / Only Cold Air Blows
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?

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?

On occasion the heat on my mk6 golf will start to blow cold when turned to the max click. Turning it back one click will cause it to start to blow hot again.
Friend at the dealer said he thought there was a software update for the hvac controls ....
Saab - 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.

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.

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 ...
View 1 RepliesElantra XD (2001-06) :: Heater Not Providing Hot Air / Radiator Hose Leaking
I have been encountering issues with my heater not providing hot air when the engine is idling. My Elantra has around 121K miles on it. I have not replaced the thermostat, water pump, timing belt, radiator, radiator hoses, or done any coolant flushes.
I checked the overflow reservoir and radiator. I didn't see coolant at top of the radiator so I topped it off as well as the reservoir. It seemed to have fixed the issue for now but I had this similar issue about 5-6 months back. I also topped off the coolant and things have been fine until now.
I checked the hoses and squeezed them to see if I could see any notable leaks but didn't see anything. I checked the overflow reservoir tank and line and nothing seemed out of the ordinary. I also checked the top of radiator to visually inspect for any notable cracks but didn't find anything. Also to note, the coolant inside the overflow bottle was bright green and not discolored.
I did however notice a lot of white chalky residue on the bypass hose below the upper radiator hose and the engine block. My guess is that my upper radiator hose is slowly leaking? Leaking in the thermostat assembly? And I also noticed a tiny puddle of coolant below the lower radiator hose at the engine block. See the pics below.
Ford F-150 - 1997-2003 :: 2001 - Radiator Leaking Antifreeze?
Went to start my truck to leave work yesterday and blew the coil on #2. It's happened before and I can fix that. The other weird thing that happened was that the radiator leaked out some antifreeze. Not a lot, but a good 2 foot puddle. The reserve was still full and it leaked from the passenger side at the bottom (below the upper hose). Upper and lower hose show no sign of leakage. I suppose the drain is on the lower end of the passenger side of the radiator and it leaked from there. Would the compression from the engine cause that to happen? Or is it something more, dare I say, like the head gasket blew?

2001 F250- V10... Lower radiator hose has coolant leaking - Right now I cannot tell if its the hose or the radiator itself (hoping not) - I tried to take the clamp off and it broke - Any tricks to removing the hose? its on there pretty tight.... I guess if I don't want to save the hose I can rip it off with a pair of pliers but before I do that wasn't sure.

View 4 RepliesFord F-150 - 1997-2003 :: 2001 - AC Was Cold But No Blower / Intermittent Heat
I found no heat last week in my 01 F150. The AC was cold but no blower. The heat was there but no blower. I replaced the blower motor resistor. Result: i believe a FEW of the speeds worked when turning the fan speed switch...but was intermittent. It would blow L, M, H, then nothing. I jiggled the know on the dash mounted switch and heard it on/off, on/off the motor as I jiggled. I DID notice that when I disco'd the connector off the resistor the HIGH speed worked. Is the switch on the dash perhaps crusty ? Or should I be looknig at the motor itself.
View 4 RepliesBuick - Parkavenue :: AC Vent On Driver Side Blows Cold But On Passenger Side Blows Extremely Hot Air
I have a Buick park avenue 1998, 3.8L V6 engine. the problem is: The ac vent on the driver's side blows cold air but on the passenger side blows EXTREMELY hot air. no matter how cold or hot you set the ac it blows at the same temperature on both sides. Florida heat is setting in and my passengers are melting. I am really hopping that is not something to bad and that I can fix it myself. Tip: this started happening after i had the alternator and the battery replaced.
