Sorry ... my 2002 MPV has not had that problem ... well, I hardly use the windows anyway.
But that sounds like an actuator issue or could be mechanical.
Do u hear a sound when u press the up/down button?
Are the gears engaging at all?
If there is no activity at all, then the issue is not mechanical.
#8195 of 8223 Drivers Window
Dec 19, 2009 (12:54 pm)
My 2003 MPV's drivers window is VERY slow in the winter time - at going up. I had them check it a couple years ago and the dealer said it was the old 'normal' thing! Ugh! I swear some cold mornings - as I park in a ramp - mine won't go up either. It groans really hard. I heard that some Toyota Sienna's have had the same issue too!! WOW! The previous generation version. So, Mazda is not alone.
I checked an 06 they had on the lot and it was a bit slow too...so it's the way they're made I guess.
#8196 of 8223 2003 MPV rough idle
Jan 14, 2010 (10:34 am)
My 2003 Mazda MPV ES with 88,700 miles on it has started idling very rough, but only when warmed up. It starts in the cold fine and runs great after that, except for idling. My check engine light is on and the codes are P0171 and P0174, System Too Lean Bank 1 and Bank 2.
The Auto Zone guy (who read the codes for me) told me it is probably the O2 sensors but another forum said it might be a vacuum leak. Thoughts?

Sounds like the idle air control valve to me. If so may just need a good cleaning.

I had that same error codes way back.
Initially - they thought it was the O2 sensor. The MPV has two ... one before the catalytic converter - and one after it. Combined, they cost about <$200.00. However, further testing and pleading from me showed something else instead. The MAF - mass air flow sensor was dirty. We thought it needed replacement - which was not too expensive. The tech guy simply cleaned it and the error codes never came back. About 15-20K miles later, slightly same error codes came back --- 1. The EGR - hose / valve (made of rubber or PVC) was in need of replacement (again). It was initially replaced at 35K due to a recall. It was again worn out - the part was about <$70 but the labor was relatively high.Check the Mazda MPV recall history on this one. I am might be wrong about the exact name. 2. The MAF needed replacement. I cleaned it on more than one occasion but at 120K mileage - I think it was beyond its useful life - so I replaced it. The problem has not come back since - am now at 132K. I did notice that all these problems crop up during the cold winter months ...

Yep, that issue sounds just like what our '02 is currently doing...although not today. I am now expecting the mechanic to find the PCV hose ruptured. Guess if that's the case, it lasted 5 years (or about 50k miles) in our case.
#8200 of 8223 2003 MPV - Rough
Jan 14, 2010 (9:49 pm)
I have had that happen when it rains heavy or I drive in a rain storm. The front spark plug wire get's water seaping into it and the light comes on and it bucks real bad. After a day, it dries out and all fine. I know I could replace that cap/wire but it's not cheap. Those other replies are all similar to what I have otherwise although I didn't experience rough running with the catalytic mess or other items. Just the moisture problem. Been doing it since it was new too.

I've had code P0171 a couple times, it has always turned out to be the Mass Air Flow sensor. There are a couple fine spring looking coils in the MAF that need to get sprayed with "mass air flow sensor cleaner".
The MAF is just downstream of the air filter. It can get lint and so forth from a new air cleaner.
But, your rough idle could also be due to the PVC hose collapsing and cracking (which creates a vacuum leak, and a lean condition). That hose can be about a $100 item...I've had to do mine twice in 88k miles, once as a dealer recall, once on my own wallet.
Jan 27, 2010 (11:02 pm)
anyone attempt to change these? I've got an '03 with 88,000, it threw a code misfire P0301 (misfire cylinder one) last week and is not running as smooth as normal. I'm guessing it's due for an early spark plug/plug boot replacement.
What plugs are you using? Rock Auto shows a bunch of options, looks like Bosch has an expensive Iridium replacement, super long life, etc...

Could be the coil. I've read the best plug for the MPV is the OEM plug, Motorcraft or the NKG plug. Too bad on the 301 code, that's a hard one to get to.
