This site is dedicated to the Toyota Granvia, a luxury four-door people carrier (MPV) available in the UK as a grey market import from Japan. If you have general or mechanical questions about your Toyota Granvia, this is the place for you.
I have seen a post on here from way back regarding the drivers electric seat, but there seems to have been no solution found. When the seats forward and back switch is pressed the seat twists because one of the rods that moves the seat forward and back does not move. I know you can manually move the static one but I need to know firstly where is the fuse for the electric seat situated ?, there is no mention of it in the manual. Secondly are the two rods that move the seat forwards and backwards running on one or two motors? and finally could the problem be a wiring issue and not the motor? Any input would be much appreciated. Dave
As far as I could see only one motor on the door side of the seat connected across towards the passenger seat with another rod, mine stopped working so I did investigate but to no avail, did try and tighten the joints up but would think a cog has sheared inside of the small gearbox one day will strip and look unless someone else goes first
We had a similar problem with our Granvia. Wellhouse showed me the wormscrew that wears out and causes this- its made of plastic and not very strong - it can shear if it encounters any resistance. I think there is one on each side of the chair. They said they could replace it with an new one but it would be a lot of money (£150 ?). They did try fitting a second hand one but that failed. Surprisingly both me and my partner find the position ok for driving despite being very different heights- we just have to vary the steering wheel height. Paddy
Hi, I have the same fault on my Granvia. Can you please tell me how you sourced a replacement part as all I can find in looking at parts is the entire motor mechanism for £150+ and that seems a bit excess when all that is worn is the plastic bevel! Many thanks, Paul
Hi, I have managed to get a little plastic gear from the US. Now I need to get the mechanism apart. Has anyone any clues. Obviously getting the seat out is easy. But it is what do I do then as the whole thing appears very complex.
