2004 Mazda MPV heater stopped working.

My 2004 Mazda MPV's heater suddenly stopped working. I had it parked for two days in just below freezing temperature. It was very cold and it took me a couple of tryes to get it started, Once I did I drove for a few miles and I noticed that the heater only blew cold air. Unfortunately I have to take it to the dealer next week to change the ignition coil, which failed and sometimes it looses power. It takes removing the engine to get to the back spark plugs and ignition coils, yikes. So I did not expect a heater problem as well to ad to the costs. Any ideas?

Check the valve or linkage that allows coolant into the heater core.

SOURCE: #5 cylinder misfire

I have a corolla and had #4 cylinder misfire also diagnosed at autozone. After changing the spark plugs, problem persisted, along with the same error code, so they recommended changing the spark plug wires, and that is what fixed it. I would have changed the rotor cap too, but was low on dough. Glad that was not the problem.

SOURCE: abs light stays on/strong smell

Check the E-Brake, make sure that the ebrake is not engaged and that it is fully disengaging. If that is not the problem, then there is something with the brake calipers or rotors that are not allowing your brakes to fully disengage

2000 Mazda MPV Starts & runs won't go out of Park Shifter handle moves won't change gears??

I had this issue in the past. All I did was to replace the brake switch. This part is located behind the brake pedal. Btw, if you this run into this issue again in the future, you can always push this switch with your finger and it's located on top of your steering wheel enclosure, this will disengage the shifter.there is a small rectangle shape cover that you need to remove first.

I had my 2000 Mazda MPV jump started after I left my lights on and killed the battery. The next day my radio and speedometer are not working and I have to manually shift my car to get it moving and it...

I think it may be an electrical issue but I think it's just a fuse. There are 2 fuses I would check. One of them is a 15 amp fuse inside the fuse panel inside the vehicle (see fuse layout below) and the other is a 40 amp fuse in the fuse panel under the hood of the vehicle in the engine compartment (see other picture below). I marked the fuses to check and hope this is the problem.

2004 mazda mpv. suddenly unable to shift from park into any gear. what happened?

Probable culprit would be the electric solenoid that releases the gear shift linkage when you apply the brake pedal. Since it's electric, a dead battery will cause the same result. Check to see if your brake lights are working. If not try replacing your brake light switch as this also gets power to the above mentioned solenoid.

This is a safety feature to prevent children from accidentally putting a car in gear.

Good luck!

My mpv is overheating and not pttin out any heat in the cab. I replaced the stat and the problem remains...what is the solution to this...btw, the h2o pump isn't leaking either..

Are there clogs in the system that may be fixed by flushing and filling with coolant?

Do both tubes leading to the heater core get hot when the engine is hot?

If not, then the heater core is plugged up.

Otherwise, if the two tubes are hot leading to the heater core, the blend door is not opening.

Also, is the radiator's cooling fan operating when it gets hot?

These are a few questions to ask.

Good luck on this repair.

96 mazda mpv minivan 165k mi. Ran fine until one day just died.Had towed home.3 mech.tried diagnose gave up wouldn't start-turns over-no start. Last mech.replaced timing belt&idle pulley. Still no...

I was browsing unsolved problems. If you still have the problem, I'll try to help you. But it's going to be awhile trying to communicate back and forth. First...Check the engine for spark. Take off a plug wire and stick a screw driver in the wire end and place the metal part of the screw driver next to something on the van that's metal. Have someone crank it over for just a second or two and see if a small spark jumps from the screw driver to the metal part. I'll check back for your answer.

What does it take to repair a parking brake on a Mazda MPV for 2004. Is there such a thing as a brake shoe for the emergency or parking brake?

If this is an automatic, like I think it is, you don't need parking brake.
But if you still want to fix, the parking brake uses the rear brakes through a cable. The cable might be rusted or broken. This is the most common rpoblem.

Mazda MPV 2004 - Stutters, check engine light came on

chances are fairly good it's the coils - I've posted about this on Edmunds. the OEM design is truely idiotic & has a vent that allows moisture down into the plug well - that shorts the spark & causes misfires. On our 2004 MPV I got away w/cleaning & drying them extremely carefully then sealing the vent w/silicone as a temp measure, then ordered perfect replacement after-market coils off ebay that sealed the wells & stopped the problem -and- were a tiny fraction of the OEM price.  good luck, BK
