Mitsubishi Outlander Heating Ventilation and A/C



  • craviotfcraviotf Posts: 2
    Hi, I just bought an Outlander 2007 LS with manual A/C and when the A/C its on the engine vent starts and shutdown in very short time.
    When the car is idle you can hear the vents very loud for about 10 seconds, they turno off for about 30 seconds and then again.

    This is normal for the car??
  • It is normal.
    It allows the AC to produce cold air in very little time compared to other vehicles.
    You can reduce the frequency and time the fan runs by NOT selecting max air if you have a LS. If you have the premium AC with the temp setting I dont know how you dont select max air. Regardless its not something you need to worry about, its not hurting anything.

    I am about to hit 6000mi with my 07 Outlander, so it means another oil change. I do my oil change at the dealer since I am very confident of their service, and the service manager is a friendly guy. They did both the front-end knock and wind rattle issues done without any problems so far.

    I haven't been using the A/C that much until recently when summer got into full swing. I noticed about the A/C fan/clutch cycling often (every 15-30 secs) which is normal as I've read from the previous postings here. So I've no questions about that, just a bit surprised when I started noticing it.

    The real issue I have right now is about the cold air being not distributed evenly. Pictures paint a thousand words so please refer to the picture below. Everytime I run the A/C, I only get cold air blowing through the vents on the driver side (shown in GREEN circles). The passenger side vent (in RED circles) does not get cold air at all. Even with blower settings set to blow on the widshield or bottom/foot area, only the driver side gets cold air, not the passenger side. I tried to set set the blower to AUTO, still the same. A/C mode to auto and manual, all the same. And this is with a passenger on the the passenger seat, just in case this vehicle is that smart to figure that out.


    Any thoughts or similar experience? Share your experience so at least I can relay to the Service Guy if any other vehicles are experiencing the same problems, and this might actually warrant another TSB if proven to be on most vehicles.
  • I dunno, I havent noticed this, but I cant stand the constant fan clutching. Plus the condensation is ridiculous. There's a puddle under the car within 10 minutes after running the AC. Not sure if this is normal or not for AC, but never noticed it on my last car, a toyota Spyder.

    Turns out the A/C lost most of it's refigerant. The vehicle somehow shuts the passenger side cooling off and diverts all cool air it can make to the driver side, well, that's what the service manager told me anyway. I was afraid they'd start ripping off the dash and fix something in the cooling ducts but it wasn't that bad as I expected. Now I get goosebumps from the cold even when it's 100+ F outside. The Outlander has one of the best A/C I've experienced in a car, so I can really tell when my Outlander started to lose it's cooling power because the cabin temp isn't as cold as it used to be. And to add, despite the frequent A/C cycling, which the Outlander does to save on gas because of the A/C's efficient cooling, I barely noticed a drop in my gas mileage when the A/C is on.

    Well, condensation is always good when talking about the A/C. Looks like it's a good sign of a good A/C doing its job.
  • On my 2003 Mitsubishi Outlander, I recently noticed that when I turn to the left there is a sound coming from under the dashboard on the passenger side that sounds like I'm driving through a puddle of water. After paying closer attention I saw water dripping from under the dash when turning. When the A/C is off, there is no noise or water leaking. It appears to be coming from the A/C device but I can't tell exactly where. Any idea what might be causing this, the fix and cost?

    Without knowing exact locations on that year's outlander, here's the problem. The AC condensor under the dash has a drip pan for condensation. There is a hose attached to the drip pan that drains the water out under the vehicle. Your hose is blocked or kinked. You need to find where the hose on the passenger side and clean it out or make sure it is otherwise not kinked. Sometimes looking from under the vehicle, you can find the outlet end and work back from there.
  • I had this same problem on my old Honda Accord. Once you find the hose you can try squeezing the length of it to unclog it or straighten it if kinked. In my case it was clogged from leaves and debris.

    My husband and I have noticed that at times when our 03 Outlander is in park the A/C begins blowing air (not cool air), then all of a sudden you can drive and the cold air will start blowing again... any thoughts to what problem we are looking at here?

    I would start from coolant, if it hasn't been replaced yet. The other simple one to check/replace is thermostat. The reason computer shoots off AC compressor is too high engine temperature, so additional sources of heat are switched off. As soon as you start driving, cold air from outside help with cooling, and AC can run again.

    I've something similar on my '99 Galant. Both AC and heat seem to not really be working right when the vehicle is stopped. I notice it more at long stoplights while in Drive v. in Park but then I rarely sit for long periods in Park. What seems to work for me is to not run the fan on the highest setting. On lower settings the problem doesn't seem to come up.

    I can't beleive this problem has been going on for so long and Mitsubshi will not do anything about this. I have an 07, and the heater is a BIG problem for me. I live in northern Maine, -30 F has been the temp for over 2 weeks now. I get no heat or very little when running idol. while driving, again very little heat comes out of the defrost, which makes my windshield freeze. How have you resolved your problem?

  • Did you ever find a fix.? My daughter is beside herself (and cold) At corporate they told her it was a 'characteristic of the car' and they couldn't do anything

    We've had some below zero weather here lately and I was driving the '07 Outlander. (my wife usually drives it.) I commented that it took forever to warm up and she said it's always been that way.

    Even the engine seems to take longer to warm up than it does on my '05 Lincoln and when it's warmed up it still doesn't give great heat.

    I'd call it adequate at best.
  • My daughter is distraught with this problem- and also, when the car idles heat stops working. The top honcho at the dispute center at Mitsubishi told her it was a 'characterisic of the car' and not repairable-- can you believe it????
  • I have the same problem with my 07 Outlander which my husband just bought me in June 2008. I live in northern Maine also, took it to the dealer few weeks ago and they made a call to the Mitsubishi hotline. Came back to me saying it was a normal characteristic for the vehicle and to keep switching it from recirculate to defrost which is a pain in the butt and doesn't always work. The thermostat reads correctly, so that isn't the problem. I contacted another Mitsubishi dealer, faxed them my report I got from the 1st dealer and they told me sounds about right and nothing they can do for me either. I am still driving this vehicle but is very frustrating especially when you have a little child in the back seat wrapped in a blanket. I hope someday, someone has a fix for this. My husband stated that if he would have known, he wouldn't have bougth the vehicle.

    In my 08 ES when I have the blower on the slower speeds I get a rattling type noise from the blower. Anyone else have this or know what it is? Thanks...

    Should be quiet, have the dealer look at it.
