Ford F-150 - 1997-2003 :: Heat Started Blowing Cold / Temp Gauge Showing Lower Then Overheated
Dec 9, 2016
Was driving my truck I have a 97 f150 4x4 4.6L, btw. The heater started blowing cold air and I looked at the temp gauge but it was showing lower than it normally does and then, after a couple of miles or so I looked at the temp gauge again. By this time I was in my driveway. And it was overheating it might have been that way before I looked at the temp gauge again. But any way I opened the hood didn't see any leaks, all my hoses were hot except the top heater hose. Also checked the oil it was full and coolant was too, what this could be? Sounds like a t-stat to me? But could be worse. Also forgot to mention that the oil had no signs of water in there nor the expansion tank cap !

2001 F150 5.4 4wd - AC not working but when I turn the temperature dial to the blue side and turn on the fan, super hot air comes out of the vents or wherever I direct the fan to blow (Floor, defrost, etc) I know it shouldn't blow ice cold especially since my AC doesn't work but.....shouldn't I feel a temp change coming from the vents when I move temp dial from the red area to the blue? It's max heat wherever I have it set.

My '97 F250 5.4L is pumping coolant on to the top of the motor which is burning off causing it to smoke like it's overheated but the temp gauge is operating in normal range. I'm losing coolant but can't see where. It's not going to the ground. It just pools up on the top of the motor. I've already replaced the water pump in the last 2 weeks because of the same issue. It stopped for a few days but now it's back again. Bad water pump from O'Reily's or is there some other issue here? I've checked while the motor's running and can't see where the coolant is coming from and there's no coolant coming out of the bleed hole in the top of the new water pump. I need this truck up and running.

I have a 2002 f150 supercrew 5.4 liter. About mid winter my heat suddenly went from hot to lukewarm. A check of the fluids shows all is good. I use my truck solely for work so I didn't bother with it at the time. Summer is here and my AC blows kinda cold, at best. I can hear the blend door moving. The temp control does make a huge difference. It just doesn't get real cold or real hot. Not like it should.

I have a 95 ford f350 when u run it with the heat on the truck temp gauge says its overheating the heat will go from nice and hot to ice cold as soon as the temp gauge goes up to the red. I replaced the thermostat also checked for coolant leak cant find any but truck has strong anti freeze smell and the radiator keeps going low on coolant.

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?

My 2001 f150 super crew, the heat only works on speeds 1-3. All 4 speeds blow air fine, I'm talking about the temperature. not the blower. Could it be the heat resistor?

I have a 1997 Ford Expedition, 5.4. My research indicates that fuses 2. 19. 29 are associated with the instrument cluster (IC), could you identify their specific function in relation to the IC? My IC gauge lights are not showing and my alternator is not consistently charging. The blinkers, battery, oil, brake, and ABS indicator lights are showing in start. Regarding the alternator, my research indicates that a failing alt light on the IC may cause the no charging condition? As a note, I have a brand new battery, brand new alternator, brand new 3 pin wiring harness. Also, when the alternator is not charging and I connect the a jumper from the exciter wire directly to the pos battery terminal, the charging starts.

Ok I have a 97 f150 4.6L. My radiator has been bad for a while. With brown rust color. I replaced my radiator, thermostat, new upper and lower hoses. Everything runs great but I have no heat. I flushed everything including the heater core. Core is not leaking into cab, and both heater hoses are cold. What should I do next FYI heat worked great until 5 days ago.

My radiator gave way on the highway, and by the time I noticed it the temp had maxed out the gauge and all the coolent was gone. So, I only have 90k on my '94 Camry and I'm debating whether to tackle repairs and perhaps a rebuild if necessary. What's the likelihood that there's damage to the rings, bore, crank, valves, etc due to the overheat? How much repair am I potentially looking at and what can I check without a tear-down? I'd like to get it running again since I just invested in new struts, brake calipers and MS and tires (not to mention that it has been pretty-much worry-free until now), but I want to know whether it's even worth my while.

Temperature gauge stuck past hot since my engine overheated once due to a broken water pump belt...
How can I fix a stuck coolant temperature gauge?
Its on a 1998 Mercury Mystique.

I have a 97 f150 that only blows heat and I am wondering if the blendor is bad or is it something else that is causing the issiue

Every thing was working great then the AC quit. I ran through the air selector and all I can get is panel and defrost with no heat. I checked the vacuum line on the passenger side engine compartment and it looks good. Oh I also took the control apart and 3 of the five holes had vacuum to them.

'05 Ex overhead console temp is showing -40 deg... Had the board out looking for loose diodes, didn't see any. Have any of you ran into this before?

My temp gauge (which very seldom deviated form its position) is showing above normal temps. Yeah its over 90 here but this is unusual for my car to run hotter. I put in a new thermostat about 3 years ago. I've also been adding water/anti-freeze because there was a small leak (that I finally found in the hose) that I corrected. Could it be that my mixture isn't a 50/50 mix or is it my thermostat again? They say they don't last long anymore???

As I was driving, my break light came on and my ABS light came on. Also, the temp gauge stopped registering and my AC stopped blowing cold air. Is this a familiar problem or do i have a legit electrical problem.

Problem: The exterior temp. gauge is blank.
It used to fade in and out and I discovered if I pushed the button that switches from degrees F. to degrees C. it wold come on for a bit, but no more. It's just blank.
I think I've seen a thread on here about similar issues but I was unable to find it. I'm also not sure how to take the overhead console off yet. The console consists of ext. temp gauge, sun glasses compartment, and compartment for a garage door opener.

I have a 2002 supercrew 5.4 triton. My coolant temp gauge is acting up. When it starts up its obviously in the cold range but when the truck begins to get up to temp, the gauge only goes up 1/4 full. What it can be?

I just bought a 97 f-150 from my dad, there are some electrical issue's but the main one seems to be battery drain.
I have noticed with the truck off key in my pocket, the a/c doors keep trying to move and the a/c head has power to it.
I know the engine has been replaced, with about 20k on it.
The temp gauge pegs w/o getting hot, and it even turned over once while we were getting in the truck. Again key in pocket.
