Most probably power window motor. Can get it change within rm100

Not sure if the Persona Elegance has a different design, but the window regulator for mine is metal. The symptom I have experienced so far for a failing power window motor is that it only likes operating once under hot weather before going dead. It comes back to life when it has cooled down a bit. Replacing the window motor is a very easy DIY task.

Yes, mine is pre-facelift. The door panel is held on by screws, all of which should be easily found (5 for front door, 3 for rear). Once you remove all the screws, you just need to slowly pry the door panel off the door. I would suggest running your fingers along the door panel to slowly release it so you don't break the door clips. You can start by pulling the door panel off from the top.

The only thing that you need to worry about is sticking the weather sheet back. I would suggest buying windscreen sealant as well because the butyl strip that holds the weather sheet has probably dried up after so long. Also, be careful when you remove the power window motor from the regulator. The part where the power window motor sits on the regulator is spring loaded.

Ya... Half is better but mine will still jumping. But not frequent as 2 sec.. maybe 30sec - 40sec once... Sienz !!!

The regulator is sold separately. Just to go any spare parts shop and ask them for windscreen sealant. It should be between RM10 ~ RM20 and what you'll get is a roll of black sticky stuff.

I don't know anything about a bracket, but my last memory of the power window assembly is it's motor + regulator only. My problem was with the motor. The speaker should be mounted on the door, not on the door panel, so taking the door panel off shouldn't affect it. The connection to the driver side console can easily be plugged out after you remove the door panel. You can also remove it first by removing its screw and then prying/pulling it out of its slot. Finally, you just need to slide the door panel upwards off the door lock at an angle.

That is the window regulator for the rear windows. Unless they changed it, the front should be the scissors type, like this:

I'm not very clear about the rear window regulator. I think for some batch they were using scissors style window regulators as well for the rear, before it became the one with the plastic. If you want to know, just remove your door panel and you should be able to see the window regulator. The job of removing the door panel is really easy. 5 screws, pry it off, and remove the connection for the driver console.

Edit: I don't remember if the rollers on the scissors type regulator are plastics or metal.

I'm not sure about what bracket they are talking about.

The location of the 5 screws:
a) 2 securing the door handle cover
b) 1 securing the driver console
c) 1 towards the side mirror
d) 1 at the side of the door panel beside the door lock

You planning to DIY it?
I notice you mentioned BHP Kuchai Lama. If you're reside nearby, I intro you to one of the workshop at Happy Garden.

any good tyre shop to recommend at ampang area? last time kena conned with chamber screw stuff like that, dun wish to go back to that shop again

Don't think so... I think you haven't found a good and honest shop. I believe that our car's alignment should be done easily considering that the toe for all four wheels can be adjusted without requiring any parts to be changed. When my car was fitted with camber bolts last time (also kena con), they just adjusted the reading to be 0 with the car in the air. But this was on the pretext that the tyres will wear out faster on the outer edge, which doesn't make sense since a more positive camber will make it worse I think, in addition to having bad/aggressive toe adjustments.

My current all round camber readings are - 1.xx deg + and the shop I go to still can make it straight. The toe reading is also affected by the camber, but as far as I can see, as long as they can get the toe adjustment right, the car will go straight. When I first switched to sports suspension, the camber reading was -2 deg left and -3 deg right. The car's alignment still could be done correctly without any adjustments to the camber.

my persona reverse sensor/light is always on when i switch on key(free gear)... anyone know whats the problem?

Just saw about this news in Chinese newspaper, it was not true. I could not find the article in english paper.

But the article said you need to connect negative cable to engine instead of negative terminal at battery.

where to change and how much budget? brand of the battery?
my location is equinne park, is there any nearby shops to suggest?
