#13 of 19 How do I get heat in the back seat by ken90 Jan 01, 2009 (4:33 pm)
We have a 2000 Mazda MPV, and can not get heat to the rear compartment. All we get is cold air. The owners manual does not explain how to get heat. Can hear and feel the blower moving air. any ideas?

Replying to: ken90 (Jan 01, 2009 4:33 pm) You need to have the rear heat option in order to have rear heat. If you had heat before and now don't, then you have an issue.   You can check underneath the van on the passenger (right) side below the sliding rear door. You'll see aluminum tubing for A/C going to the rear wheel well and if you have rear heat you'll have black steel tubing. They may be wrapped in foam along the way and will have 2 tubes each.   -Brian Replies to this message: ken90 (Jan 04, 2009 7:13 pm) subearu (Jan 05, 2009 4:02 am) foxmike (Mar 24, 2009 9:13 am)

Replying to: subearu (Jan 01, 2009 6:48 pm) Brian. Ok , I will check for the tubing. There is an overhead selector for fan speeds 0 thru 3 (I think) same as on the control at the front operators panel. So I presume the heater feature is there. What kind of problems can there be with the rear compartment heat? Replies to this message: subearu (Jan 05, 2009 4:02 am) foxmike (Mar 24, 2009 9:13 am)

Replying to: ken90 (Jan 04, 2009 7:13 pm) If you have rear heat, the rear heat tubes can corrode in the wheel well and eventually leak. So, you might not have heat for that reason. You might even smell and see coolant leaking outside. Check your coolant level in the bottle up front, as you don't want to be w/o coolant in the engine.   There is a Special Service Bulletin for that leak, that extended coverage to 7 years. Replacement tubing and removal of the plastic guard in the wheel well is the fix.   Another possibility is that the flow switch up front behind the engine has the rear heat tubes getting no coolant. Possibly for the reason above, or perhaps because of previous work. Yet another possibility is that air is in the lines and needs to be "burped" out.   -Brian Replies to this message: foxmike (Mar 24, 2009 9:13 am)

Replying to: ira8 (Oct 20, 2008 5:05 am) I know exactly what your problem is....its called a AIC valve also known as a Automatic Idle Control Valve and they can be bought from most any parts store...price range 75 to 200 bucks and you can change it out yourself as it sits right on the top of the engine compartment.... its small and it has one elec cord to it I think.....this will fix your car from stall but you will need to get someone with a diag computer to reprogram your computer for max performance.....it is not immediatly nessesary to do the programming for the replacment to fix the problem but it is something you will want to get done.

Replying to: choquer (Dec 12, 2008 11:02 am) Not sure if this will help you folks, but this is an ongoing issue with our MPV. Pretty much every time it goes into the shop, it comes back with no heat. The solution for us is the water valve. See this link   http://www.mpvclub.com/tsb.php?id=152   For whatever reason, the tech always like to fool with this valve...
