SOURCE: 2004 mazda mpv- rear heater fan only works on high

My bet is that there's a relay at fault... but first: have you checked the fuses? the high blower speed draws a lot of power, so sometimes it's fused separately from the other speeds. This means that your fuse for the slow blower speeds could be blown. Also, because theblower draws so much power, you'd need a HUGE switch to switch it directly, so they use a low-power switch inside the car, and a relay (usually under the hood, but sometimes under a seat (check your owner's manual) to do the heavy work. These are often split the same way, with the high blower on one, and the slow on the other. These are the things that are easier to check, but it could just be that the switch is bad. Mid 90s Land rovers and Range Rovers have the same problem, where the only blower speed that works is HIGH, making the cabin sound like a wind tunnel... Just the switch. The switch can be a pain to replace if you do it yourself, but do check the fuses first, and see if you can find the relays. if the fuses are okay, and you find the relays, try to find the one that's for the fan and swap it out, it shouldn't be more than 3-4 dollars from an auto parts store, just bring in the old one to match it, or swap it for another relay that's nearby and has the same pins. If the swap works, just remember to get another relay, because the one you "borrow" from another circuit could be the door locks or the headlights or something else important....

SOURCE: mazda 2003 MPV door locks

I just fixed this same problem. It happened to me 3 different times in a month so I got good at it. Before you dive into removing your door try this. Pull the door handle and release it letting it snap back several times. The problem is a half open door latch that won't let the door unlock. Do this as aggressively as you can to attempt to get the latch to return to its original position. Check the door lock between flicks.

Ok, if that didn't work, here is how to remove the door.
1. Remove the screw behind the door latch, you will have to pop the plastic cover off first.
2. Remove the rubber insert in the door handle
3. Remove the screw that is now visible
4. Now remove the window/lock control module, the back is free but the front has a plastic lip so lift the back up and pull towards the back of the van.
5. Remove the clips that attach to the lock and to the window controls (these can be a pain)
5. (Optional) Remove the bracket that held the window/lock control module

At this point your door is basically free, it is only held in place with plastic clips that can be easily forced off. If your door were open you would simple pull the bottom of the door out (hinged at the window) and lift it off. But since we can't pull because the door is closed we have to force it out.

From here it is pretty simple. Move the seat all the way back and tip the seat way back. Lift the door panel straight up. You will be breaking 2 plastic clips from the rear part but once you do it just pulls out. This is not that easy because the space is limited but just keep pulling and force the rear end of the door panel past the b-pillar. Once you do this it is free.

Have fun and try to keep the black gook from getting everywhere.

Oh, to fix the door lock just oil/grease it and manually move the mechanism several times.

SOURCE: Engine warning light on Mazda MPV 2002

There seem to be 4 sensors along the way in the air intake and emissions system.

My Check Engine light indicated a bad sensor 1, bank 2 code (I think).

I had my mechanic replace the sensor that was indicated as faulty... cost = $191.

Then the Check Engine light came on again (with a different code), and I had to leave the van with him all day.

Cost to replace and install that sensor = $115.

My advice: if the Check Engine light stays on *AND* your vehicle is riding rough, get it fixed.

Otherwise, put a piece of tape over that Check Engine light and save a couple hundred dollars!

Hope this helps, I do trust my mechanic fully.

2003 Mazda MPV heater blows heat, then blows normal temp air, then heats and so on. Trying to find what is the problem. The unit is blowing air all the time but the temperature changes within seconds.


Have you checked your antifreeze level? When the vehicle is cool check the level and top it off if its low. Read your manual if you're not sure where to look.

My 2000 Mazda MPV heater fan works for 4 not for 1


You need to replace the blower motor resistor,it's in the heater box.Number 4 bypasses the resistor and all the other speeds go through it so it's the most likely problem.
