I don't know what it is but it comes on when the air is turned on inside the truck. Heat or A/C doesn't matter and its coming from rear passenger side by the window under the plastic molding. I thought it was a secondary blend door but as I know it the truck only has one.
View 1 RepliesMy heater/AC fan only works on high. how do i get the low and medium settings to work?
View 3 RepliesWhen i turn my heater on, the ac come on instead. It does not matter what position any of the dials are on as soon as I turn the blower on the ac comes on. I do not see anything obviously wrong with the controls. All turn as they should nothing is striped. I have the 3 dial control setup no auto heater controls at all. and nothing is digital.
View 2 RepliesI've got a 2004 Cavalier and when the heater is turned on it makes a clicking noise (sounds like someone on a snare drum playing over and over again) You can feel it if you touch the bottom of the Heater/AC module on the passenger side of the car above your feet. It stops when you turn the heater control to the recirculation position.
My guess is it's the recirculation door actuator motor, but I can't find it through NAPA or any automotive parts online sites, what the Chevy part number is for this, and/or a parts blowup of the HVAC module? Also, the factory service manual I've got says that the entire HVAC unit needs to be drained of 134 and removed from the vehicle to replace this actuator, does it can be done without removing the entire unit? From the few pictures it shows of where the actuator is, that part appears to be near the top (that's why I'd like to see a parts blowup if possible).
We have a 2004 Excursion limited edition with 6.0 diesel. This is a recent purchase for our family. This is our first ever Ford and our first ever Diesel.
Now that we are transitioning into colder weather, we recently tried to place the air from AC to Heater. When we tried, we noticed a clicking or hitting noise from the passenger side behind the glove box. When we stopped the air, the noise stopped. When we kept it on the AC, it stopped. Last night we tried to replicate the issue to get more info and we saw that now its stuck on heater and we lost the AC cold air. The module that is making noise is behind the glove box. It is not coming from the actuator that moves air from the feet to the vents, but it is to the right of the actuator and has a plug with about 4 cables plugged into it.
Questions:
What is this module so that I can order a new one?
Does this sound like a bad HVAC blend door actuator? (not trying to steer it that way if its not.)
Any videos on how to replace it? I only see one bolt that mounts it and it appears to be about 8 mm. Is that the only thing holding it?
Coming home from work tonight, Radio turned down, Air off/Heat off. Whats the sound coming from the dash around the radio/heater controls/ vents? Can't really explain the noise, but its like a boiling/clicking/scratching noise.
View 14 Replies2000 Expedition AWD, 4.6l ... 150K on car, 50K on trans, 150k on transfer case and most else.
The problem is, under load, there is a intermittent bearing vibration noise...it sounds like a roller bearing that has too much tolerance so it vibrates in and out under acceleration. You can feel it in the gas pedal and chassis, you can hear it, and it robs a little power when the sound it pronounced. The sound is 10x worst when towing my 6000lb boat. Gear doesn't seem to matter, but it is hard to make it happen in 3rd gear.
Diagnostics so far:
-Can't reproduce sound on rack or out of gear
-Stethoscoped all accessories - good
-added Lucas oil additive to engine oil - no change
-added Duralube high mileage goop to trans - no change/slight change?
-Aamco said it was transfer case, tear down and inspection revealed nothing, they said it was mostly pristine for a car with 150K on it.
-Inspected U-joints - all tight
The duralube in the transmission may have made a slight difference in the frequency of the sound...but it could be my imagination, it wasn't significant enough a change to be determinate.
I think I could isolate the issue with a diagnostic tool that doesn't exist as far as I know...it would be a handheld device with 4 magnetic mic sensors you could stick in various locations and watch the waveform output on the handheld... you would simply move the mic's around until you got the highest amplitude on the readout.
At this point the only thing I can think of:
-Aamco missed something
-Main bearings, cam bearings, or possibly oil pump
-Transmission bearing (Aamco says "NOT")
I drive a 2008 Ford Expedition and every time I go on long trips after a while on the road the car starts making this grinding noise when driving uphill. As soon as i take my foot of the gas it stops. It has never done it in the city, always when driving on the freeway. I can manage it if I keep the gas pedal as steady as possible but if I try to give it more gas it will start making the noise. This does not happen all the time, it is intermittent. I was told that it might be the 4x4 engaging on the front wheels but I am not sure what it has to do with the speed or gas. I have changed the spark plugs, fuel filter, fuel pump.
View 19 RepliesWas driving to the beach yesterday with the family. About 15 minutes into the trip started hearing a random clicking or tapping noise that sounds like it is right under the dashboard. There are no lights showing up and all the gauges appear normal.
The sound occurs randomly and the car doesn't have to be in gear. The only one we haven't heard the noise is in reverse (but you don't drive in that often. Will attach a video on the noise exactly.
I have a 00 expedition 4wheel drive eddie bauer. 100k miles. New tires, recent alignment, new upper ball joints and tie rod ends, recent suspension change over to passive system with new shocks. Also must note I have "newer" front wheel bearings but they were from advance auto and not the suggested Moog ones.
I have a loud clicking noise at slow speeds. def sounds like its coming from the front area. Speeds up and slows down with acceleration. brakes do not change noise other than slow it down with tires. The truck also vibrates on the highway. I notice the tires are wearing (cupping)
Is it the cheap wheel bearings? what is the best way to test for bad wheel bearings? i think they are under warranty if I can find the receipt. Anything else i should test? can it be c/v joints or something?
1999 ford expedition 5.4L ....I have been hearing a loudish (I can hear it in the cab) humming noise coming from the engine bay. I don't hear it when the truck is cold (1 to 5 minutes after starting), seems to get louder at it its peak (the more I drive). When i open the hood, the humming is coming from the intake. I am a pretty handy guy, just at my witts end right now....not sure, but I was thinking brake booster?

View 2 RepliesMy wife has been complaining about a noise from her 2005 expo.
As she drove the truck today I have narrowed the noise down to the right side of the half shaft. From looking underneath and comparing what I was seeing and hearing, the track bar is not centered. Its more in on the driver side and out on the passenger side. I had her to stand on the running board and shake the truck.
I can definitely hear a kinda cluck? It sounds like the half shaft going to the tire but at the same time the bushing on the outer tire rod end. I can't determine what it is exactly.
when you rock the truck you can definitely hear it. Its not like violent loud but i'd like to get it taken care of. I looked for some grease points but I don't see none..
2nd question for the grease points that I do see how much do I grease it? how many strokes?
Friend lost reverse and truck shakes at 35 and above seems like it needs a new transmission. What years are a match for this transmission and any other models trans match?

View 6 RepliesThe heater on my 2004 Touareg V-8 appears not to be working correctly, although the dealer has said they they "calibrated" it and that that all is well. When the ECONOMY setting is on, as I understand it, I should be receiving external air, heated/vented from the engine whenever the setting of the heater (i.e., inside) temperature is higher than the outside temperature. However, even when there is a difference of 10 or more degrees, I cannot feel any heat coming from the vents.
Tonight, it was around 58 according to the thermometer on the dashboard, and I had the heater set to 70 -- NO HEAT. It required setting it to 74 before I felt anything. When the Economy setting is off -- when the heat is run through the compressor -- I get somewhat better heat, but the principal difference is that it happens more quickly. It still requires a spread of MORE than 10 degrees to get ANY heat. This happens in the winter and on cool nights during other seasons. Why should I have to have the heater dials cranked up to 74 - 78 top get normal heat?
My Prius v fan for the heat started this low bass sound when it is turned up. It seems that it causes the vehicle to race! If I shut the heat fan off while parked, the vehicles takes a few seconds to return to "normal".
View 5 RepliesMy 2006 BMW 530i's heater fan sounds like it has a bad bearing. The noise is similar to that of a leaf hitting a fast moving blade. The noise is intermittent and seems to be worse when the weather is cold. The noise gets louder when I turn to the left and quieter when I turn to the right. When I turn the heater off and restart the noise is often gone.

View 1 RepliesMy heater quit blowing hot or warm air all of the sudden. I took my mechanic and they said it showed no codes and were afraid to mess with it so I took it to a dealership. They worked on it most of a day. Said nothing showed a code as bad, they got into it and found the air going into the heater core was hot, but it was cool coming out. They spent some time flushing the coolant and said they found some sediment in the coolant fluid. They were hoping to flush out anything clogging the heater core.
