My girlfriend has a 2008 Mercury Mountaineer. Manual climate controls with one zone up front and also manual rear controls. About a year ago, her car randomly was only able to run A/C, motor speed was adjustable, and front vents only. Her stepfather went in to try to figure it out, found out...

I hope I have not over looked a previous thread regarding my issue I did search but nothing I found covered this. 2015 XLT 3.2L 4wd, 175,000 miles Over a month ago when it was still extremely hot out I got in my car after work turn it on went to turn the AC on and I had no AC no power to the...

Hello, I have a ford explorer 2012 Xlt. The passenger side ac works fine (heater and the ac), but when I input temperature LO (15*C) for both sides, there is quite a difference in the cooling between the DRIVER'S side and the passenger's side. I changed the blend door actuator, didn't work. I...

Blend actuator or another issue?

Hello, I retrofitted climate (heat/cool) Lincoln MKS seats into my 2013 PIU and the DCSM Self-Test passes and works perfectly in ForScan / IDS. You can hear the vents power up one at a time for each seat along with their relays. All the seat buttons appear in my Sync 2 / MFT display and also...

Hey! So I have an issue where my vehicle is stuck on the *vents* only. Not defrost, or the feet vents, or anything like that. Today I tore apart my dash to see further. The common plastic piece visible from the glove box is of course snapped, and the previous owner drilled a hole to keep it in...

Hi, I replaced my blend door actuator in my 2016 sport a couple months back. It worked, but the actuator seemed to ignore the limits of the damper and kept trying to open or close further, eventually causing a gear tooth to break in the actuator. How do I reset the system after replacing the...

I am having some problems with my climate control in my 2002 explorer sport trac. On fan settings 1,2, and 3 there is no air coming from the vent. However, on the high setting, 4, they both work just fine. I read that this can be related to the blower motor resistor so checked that out. It was a...

does anyone have a full diagram for the hvac power circuit for this vehicle? the high and low pressure switches have been checked and bypassed but no power reaches the ac clutch. i need to know where the signal leaves from the switch all the way through so i can find the break or problem...

Where is the ambient air temperature sensor located on a 2015 Limited Edition Explorer?

Hi, I have a 2006 Mountaineer with the 4.0. My problem is that the climate control illumination stays on at all times, even when the vehicle is off. This causes the battery to drain after about 9 hours. Also, when the headlights are on and the dimmer wheel is in certain positions, a buzzing...

Hey guys, After extensive squinting at page after page of threads going completely off topic, none I've read has helped resolve this problem. That being said: 99 Mountaineer AWD 5.0L 150k Miles, unmolested dealer serviced Charged A.C., cold lines, compressor working perectly, EATC, blower...

Hi all! I spent all day today putting on a new compressor, accumulator, orifice tube, low side pressure switch, and relay. Of course, I flushed the hell out of the system with a half gallon of solvent through a flush gun, then shop air, then flush gun. Installed the new parts, pulled a vacuum...

I have a 1996 Eddie Bauer Explore with an automatic temperature control system. The blower motor is either off or at full speed. The blower motor speed controller (not the standard resistor) seems to work as does the motor. The fan speed dial (a potentiometer) on the EATC (electronic automatic...

Hello everyone, I recently changed the blend door actuator on my explorer due to a clicking noise whenever I changed from AC to Heat. While removing a particularly pesky screw off the old actuator to remove it, my hand knocked loose a small white pipe. I felt like it just popped off, so I...

HVAC issue here. Can someone describe how this system operates for me please. I have dual zone climate control, the passenger side does not get any heat. Do I need to look for a coolant flow regulator, or a blend door actuator? What could prevent the passenger zone from getting heat? I am...

I cannot seem to find reference to this issue anywhere else. For reference - I have an 08 XLT with Manual HVAC controls (no rear HVAC) Cold air blows out of a round hole(in the HVAC Case) in the drivers side floor boards area. This happens when the heat is on. First off - I replaced the...

Hi all, I have a 2010 Explorer XLT which is in need of AC repairs. I live in the middle east and parts are difficult to get here. I've been told that the Condensor and the evaporator need replacing so what I need to know is what parts should I be getting? I can see the Condensor (part #...

Hi, I'm having an issue with my truck's AC/heat system, and I haven't been able to find a satisfactory solution online, so I'm hoping someone here can help me out. I have a 2005 Explorer XLS, and the HVAC system only likes to stay on max-cold. When I bought it about four years ago, it had a...

So if your fan isnt working on one of the settings (most likely low) then you probably need a new blower motor resistor. This video will show you how to replace the blower motor resistor yourself nice and easy! Let me know what you think! **Also, if the video was helpful, give it a...

I think I'm posting in the right thread... Anyways, Hello all, I have recently purchased a 2005 XLT V6 and there is an intermittent hissing noise coming from the rear when the HVAC system is on. It comes and goes about every 30 seconds. I have searched all over the web but have not found any...

Overview: It's a 2002 Explorer I bought it about a month ago. There were two issues, which I believe are separate problems: (1) It only blew hot air, even when turned to cold, and even though it was only ~40' outside. (2) It would blow to the windshield or dash vents fine, but not to the floor...

I have a 1998 Eddie Bauer Ford Explorer and the front air will not work. When I try to turn the air/heat/defrost on, it lights up acknowleding my command, but nothing happens. The rear air does, however, work. I have been told by different people that it could be the blower motor or the...

4.0l XLT will only blow hot air with no way of directing it. When you turn the heater on it comes out of the floor and vents mostly but still comes out of defrost and window vents. Also hardly any heat coming from rear heater in middle console. There is no A/C at all. I don't hear a sound from...
