Ford 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?

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?

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 ...

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.

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?
LS / 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?

I have a 2002 Ford Ranger 3.0L truck that, all of a sudden, has a problem with the HVAC system that blows air only thru the defrost vents even when selecting any other vent levels (defrost, face/middle or floor levels).
I did find a thread on another forum regarding this problem, only it was for the 95-01 Ranger model years, yet they say that the 2002 Ranger is not the same as those earlier models.

View 9 RepliesFord Super Duty (1999-2016) :: Heat Only Blows Through The Defroster
2002, F250, 5.4, ZF6, 140k.
My heat only blows through the defroster. I was looking for my vacuum pump, but can't seem to find it. I find plenty of diesel threads where they show it, but mine isn't in the same location. I can actuate the diverter by hand and it will make the heat stop at the defroster and come out at your feet.
I have attached images of my rig.
Were to look for the vacuum pump? Any key spots to look for failed vacuum lines? What is this?
This is where most threads say the vacuum pump should be.
This switches from defrost to floor when operated manually.
