View 1 Replies2007 f150 5.4 supercrew, average temp for the last 2 weeks was -27. I plug the truck in all night it starts good and idles down fast engine is warm. no heat after idling for 3-5 min and then try to drive it takes another 5 min for the temp gauge to hit full temp 192. then my windows fog over even the dash and there is minimal heat coming out takes another 10-15 min to clear the windows. what the "F". fulid levels up, winter front on, block heater works, not using or smelling antifreeze, brush off every last speck of snow and I still have to pull over on the highway and wait......should have kept my 95 5.8l.

On hot days, if I am doing several errands I need to worry about if my car will work after the first stop. After driving for a bit, when I turn off my car and return a short while later it will not start. The car will attempt to turn over and the battery works just fine, it just won't start. Also, another issue I think is related and connected to this is that on car trips lasting more than 15 minutes, the air conditioning will stop working. The air will blow but the cool 'conditioning' aspect will fail and I will be stuck with hot air blowing at me. The catch to this is that after waiting 2 hours for a tow, the driver was able to start my car on the first try, thus making the tow unnecessary. Obviously my car is not 'perfect' like the repair shops are telling me....
View 1 RepliesMy heat shield was loose and my dealer said it should be fine, but then it stormed and driving home I ran over a branch and when I got home I noticed the heat shield was ripped and dragging on the ground. It is pretty torn up and I'm thinking of just taking it off. Am I allowed to take it off? If so how should I go about taking it off?
View 1 RepliesRecently the temp sensor on my car goes all the way to H and then the light comes on saying I need coolant. It only seems to happen when I have the heat and/or defrost on -- if I turn the heat off the temp goes back to normal within a minute or so. (no problem using rear defrost)
First time it happened I pulled over, checked coolant level and added a little. The next time it happened I looked under the hood the next morning and coolant level was just fine.
Happens more often when I'm driving around town than on highway. Usually within about 5 minutes of driving in the morning the engine temp is all the way to H.
I've switched the fuel pump on this car more than once and made sure the fuel line isn't crimped yet it still hesitates. Also, the temp. shoots up when idling and appears to need either a fan or temp. switch?
View 4 RepliesSo I got my 2010 ISF last year around this time.... I never noticed anything a possible heat problem... So basically I've noticed that when ever I stop at red lights or at idle, my heat turns cold?
Temp is at high and the AC light is off too... When ever I drive it warms up again and works like a champ... But at idle or stopped it's completely cold....
It's scaring me.... My car is certified still I believe, this problem should be covered since it's internal?
I have an F-250 Ford, 2006, 6.0 turbo-diesel. Started noticing that my heat only works while running at 70 mph or more and the turbo is at around 15-20 psi. Now that it has gotten cold it is definitely an issue. Truck does not overheat, I am not able to feel heat on the hose after control vlave and I do not feel any vacuum on the line (grey) to the control valve. I have checked for leaks, changed out the fill cap, checked anti-freeze level, pulled control valve just to verify its position when opened (which it seems to stay open). It's getting really cold in the cab of that truck now.
View 4 RepliesI recently installed a cold sensor to my 2002 ford focus due to it trying to stall out in cold weather. It is still trying to stall out even with the cold sensor what else could be the problem?
View 2 RepliesI have a question about my 2000 Ford Focus. It has problems in the cold. When the air temperature is below -5 or so, after driving a short while (before the engine is up to temperature) if you come to a stop and the the engine go to idle it will stall. It does this while the car is still in motion (as it is a manual) and you aren't in gear coming to a stop light.
View 1 RepliesMy 2006 focus just turned 100,000 miles. Last few months as it started to get cold outside its had issues with not "holding" a start. It seems to make all the normal sounds but won't continue to run. It is progressively getting worse, ie: more frequent and takes more tries to get it started. Yesterday I tried repeatedly and it wouldn't start until I gave it a LOT of gas-this is the worst its been. Previously it would either eventually start after repeated tries or with a little gas. Even on unseasonably warm days its happening now. Both autozone and tireman say the battery (2yrs old), alternator, and starter check out fine.
After lots of online reading here's what I've tried/paid attention to in hopes of narrowing it down.
-Changed spark plugs
-Fuel injector cleaner
-Spare key
-Don't notice security light flashing when it happens or any other random electrical issues
-No strange idle fluctuations
Once its running its fine and seems to start ok for next couple tries even at cold start. Trying to narrow down from IAC valve, PCV valve, throttle position sensor, wiring, ignition switch, fuel pump, etc. Can computer codes read even without warning lights? I have noticed for quite some time that idle has a slightly rougher sound (nothing obvious) but this seems to comes from muffler end and its been in for standard service and never been mentioned as an issue...? Its never stalled at idle or sounded like it was close to stalling/strictly issue with getting it going. I'm trying to determine if its logical that repeated attempts or giving it gas build up more fuel pressure? Or more logical that lots of gas is pushing open something thats clogged up?
I have a '12 Focus and for no apparent reason the A/C will turn off and warm air enters the car for 1-3 minutes and then returns to normal cold A/C air. It doesn't matter if it's on "max A/C" which will circulate the air inside the car or just the coldest setting on the A/C, high fan, low fan, it just happens. What usually happens is that I'm driving 40 or 45, then have to slow down (stoplight, etc.) and speed up again, during the slow down is when the A/C turns off and warm air enters the car. As soon as I'm driving 45 again for a minute it usually kicks back to cold air. OR, while driving on the freeway at 60 - 70mph after about 15-20 minutes it all of a sudden stops cooling and I get warm air in the car. It's been checked by 2 different dealers already 4 times and they never found anything wrong with the A/C System. It did have an actual leak a few weeks ago and that got repaired but it still has this mysterious behavior.
View 5 Replies2007 Montana SV6 3.9. I have lots of heat when vehicle is reving 1500 -2000rpm. when idling at 700 little or no heat. recent flush, thermostat, and serpentine belt. I'm thinking, if it was the water pump not circulating enough water the car should be over heating. heat guage remains on the half mark.
View 4 RepliesI have a 2000 chevy venture with 100,000 miles on it and I just had the thermostat replaced a month ago. Now that the weather is getting warmer I have noticed the gauge going up when idling for a few minutes, drive through, etc. Is there a sensor that could have went bad when the thermostat went out that should be replaced? When I start driving again the gauge comes back down. I have noticed that the fans arent kicking on, but when I turn the a/c or heat on then they do.
View 14 RepliesThe heat works fine when driving but when car is idling there is no heat, the blower is working just blowing cold air, the temp gauge reads normal???
View 3 RepliesWhy my Passat will not put out any heat when idling? I recently had some body work done (right front fender replaced) and it seems like this has started to happen...any possibility they didn't hook up some line...???
View 12 RepliesI have a 08 Focus that will not go in reverse. I have power and speed in the rest of the gears. It will shift into reverse, just acts like neutral. Speedometer works and check engine light is not on. This is my girlfriend car she called me this morning saying she has no reverse. I drove it fine last night. I plan on looking at it and checking the cables and replace the filter. The car has 80k'ish miles on it.
View 1 RepliesWith the cold weather arriving I've recently noticed that when I have the heater on it does fine while I'm going down the road. However when I idle at an intersection the blower still works but the heat drops off.
View 5 RepliesSo for a couple weeks my car has been having issues starting. When I turn the key initially it will do nothing sometimes, take a second to start sometimes, and start almost normally sometimes. It seems to be at it's worse when I leave it for longer periods, such as after work or overnight. What happens most is that I turn the key and nothing happens for a moment, then it starts to turn over, and after a few seconds of struggling to start it turns over. It hasn't gotten worse yet, but i'd like to hear from the more knowledgeable before I go to a mechanic.
View 8 RepliesI have a 2008 Ford Focus with 122k miles in good condition, nothing ever replaced except an engine mount, shocks, and coolant thermostat and all regular maintenance.
In the last four months I have had a few instances of the car shaking during my commute. Only happens when I am either stopped at an exit ramp or stopped during heavy traffic on the highway. It can happen anywhere from 10-30 minutes into my commute. Feels like either the road is shaking from an earthquake or godzilla is standing behind it and pushing it back and forth. It's very strong but very smooth and slow. Like being on a boat. There is no vibration in the steering wheel or any other parts and no noise associated with it. It goes away once I start driving again.
I had a cracked engine mount once that produced a lot of vibration and rattling, and this shaking doesn't feel or sound anything remotely like that one, so I am doubtful that it has the do with the mounts (just had that one replaced a couple months ago anyway).
This is also extremely intermittent. Maybe once a month at most, although the time span in between occurrences seems to be shorter so that's why I am investigating. And when it happens, it's just once during my entire drive and then not again for another few weeks or so. So it would be hard to take it into a mechanic to reproduce.
What could this be? I've been thinking about getting a new car and this has me worried that I'm entering into the timeframe with this one where major things start breaking.
My 2008 Ford Focus SE hesitates at highway speeds, seems to decelerate and accelerate, sometimes more, sometime less and sometime not at all. dosn't seem to affect the acceleration.
