I’m looking for technical help or recommendations on: __power window problem
My passenger side power window switch on the drivers door isn’t working. The passenger door switch works for that window. It’s not the drivers door locking button.
The drivers window behaves normally.
My wife was putting the roof up and didn’t get it up quick enough to beat the mx5things window closure system controller and the window may have been stopped by the roof mechanism getting in the way.
I’ve changed the main power window switch in the drivers door and the passenger window still only opens with the switch in the passenger door.
Anyone have any ideas please?
Should I be looking for a fuse that corresponds with only the power from the drivers door to the window?
Are you saying you have the mx5things automated window control module installed inside the driver’s door? If so, I had nothing but trouble with them (having tried 3 different modules with Sergey) and no matter what I tried they would all lose complete control over the passenger side window. In the end i gave up and opted for a refund.
I take it you have run through the window initialisation/reset sequence then that is included in the MX5things instructions. Have you tried disconnecting the car’s battery and reconnecting?
I had a lot of issues with the mx5things window controller, early adopter before he realised RHD and LHD had different wiring. In the end, he recommended tapping into the wiring directly instead of using his adapter and it has been fine ever since.
Maybe, to aleviate the module as a possible source of the issue, it may be worth disconnecting it, reset the windows and see if that fixes the problem. A bit of a pain, but…
Yes. I’ve removed the module but hadn’t disconnected the battery since then. Tried it today. Left the battery disconnected for 15 minutes. No mx5things module at all.
Got reconnected, got in and reset the drivers window. Pushed drivers door switch for passenger window to lower and it went halfway down and stopped.
I can still use it with passenger door switch but again drivers door switch won’t move the passenger window.
It’s a new drivers door switch assembly.
Maddening!
It won’t drop the window for the soft top. I will need to drop it with the passenger switch myself.
If I open the passenger door the passenger window drops all the way, motored as if I’ve opened the window fully.
If it’s a new drivers door switch assembly, I suspect it may be faulty as you’ve troubleshot all of the other possible scenarios. Just a thought though - Mazda electrical connectors are a pain to get apart or sometimes reseat. It may be worth pulling the white connectors apart and check for bent pins in case one got caught when getting the plug/socket remated?
Good point. Cheers. I will. I also had another switch from a Mazda 2 that had the same plugs and I tried that, it didn’t work for that either but I’ll definitely inspect the pins. Cheers.
The last thing I can think of is that a (dealer) reset of the (?) BCM computer may resolve the issue; they can “factory restore” the settings and could possibly clear any glitches.
Tried this and still no solution. Found on a Mazda forum.
Found these solutions to resetting memories.
to reset ECU the easiest way is,
Take off the negative lead of the battery,
Sit in the driver’s seat of your Mazda
turn headlights on and off
press horn
Push down and release the brake pedal five times consecutively.
Wait 10-15 minutes to reconnect and ECU should be reset.
if your not sure if it worked leave it off for a few hours
Reconnect the “Negative” terminal clamp on your Mazda’s battery.
Turn your car on and let it idle for a few minutes to learn the mapping and drive like a granny for the first 30 mins! the ecu will learn that minimal fuel usage is what you want and it’ll stick to it!
coz if you floor it as soon as you do it it’ll learn that pumping fuel in is the way to go
My ND1 now has the same issue with the passenger window. I don’t have any mx5things mods or anything alike.
Yesterday when raising the roof I’ve noticed that the passenger window didn’t lower automatically. After which I’ve encountered the same behavior as described in the post (only able to control the window with the passenger switch and lowers fully when opening the door).
I’ve tried checking all the connections, resetting the ECU and doing the power window reset sequence but the issue still persists.
I still haven’t solved it. I’m avoiding taking it to Eastbourne Mazda as they have a terrible reputation. Most people say it needs the ecu replaced or reprogrammed but I don’t know for sure.
Regarding the idea of replacing the ECU, I don’t really think it has to do anything with it as in the wiring diagram the power windows are in no way connected to it. There are only two control modules (one on the driver side and one on the passenger side) with only outside inputs being the door and top latch switches.
In my opinion it’s either the issue with the control module itself (chip) or in the HAL sensors on the window motors.
I changed the motor and window regulator as a part bought from mx5parts just before it happened. I plugged in a spare for the right side that I bought and tested it on that and it did exactly the same thing
Hmm, some possible food for thought; but not having seen the actual sensors in situ, I’m probably wrong.
It may not be relevant here, but my past experience designing with Hall sensors in other applications (good and bad) in the past is that they were very sensitive to operating clearances and temperature.
Too far away and response becomes erratic, too hot and they lose sensitivity.
But when implemented correctly they can make a superbly reliable system.
Quick update. I’ve tried replacing the window switch just to make sure it’s not the cause of the issue for me. However, the issue persisted. Since I’ve just recently replaced the power window regulator, I’ll try to make a warranty claim and see if I can get a replacement. If not I’ll try to seek an OEM regulator and not a replacement to see if it resolves the issue.
