CLK Electric Seats

[WOO5IE]

Hi Guys,

I have a 2001 CLK Cab 320 and had it for 5 years and it has been an excellent car.
The issues I have at present is that the drivers seat motor stops before it has gone far enough forward to allow my wife to drive the car.
Its an Avante Garde and has 3 memory functions for 3 settings.
The seat does go back and forth manually by using the swith but not far enough forward for my wife. The memory function seems to have stopped for the forward/bacward position although some other settings seem to OK.
Also the seat doesnt move forward if you unlatch the seat back to allow some easier acces to the rear seats as it usually does.
The qustions I have is where is the memory of seats stored is it in the seat itself.
Are there sensors to detect position of seat .
Any other ideas.

Not the weather to be messing with cars but needs must.

Thanks

Quite important as its the wife's car and she cant drive it until its fixed and she wont drive my car

Sounds like the hall sensor has lost its position move the seat base all the way farward maunaly and hold the switch then all the way back and hold the switch a few seconds this should reset the sensor and make the memory work again

Hi Si

The seat does move forward via the switch manually but not all the way as it needs to.
It does move back all the way.

Is there another way of resetting the sensor.

Thanks

Strange we dont normally see issues like this unless there is somithing in the runner like a coin etc

Hi Si

I have just gone out to the car and tried to move the seat as far forward as possible via the door switch but it only went so far. I then moved the seat as far back as possible so it nearly hit the rear seat. I then held the switch for a few secs as you suggested and then moved the seat forward as far it goes and again held the switch and it now moves forward as it should way past the previous 'Stop'


So many thanks for your help.

Tomorrow I will re programme the memory settings for my wife and myself as these seem to have been reset as well.
I havent tried to see if the seat now moves to gain acees to rear seats when releasing the seat back . Will try tomorrow in the light.

The problem is more than likely what's been suggested already, hall sensor in the motor. If the switch trick doesn't work the take it into the dealer & have all the the motors in the seat re-normalized so they know exactly where they are.

You guys appear to be well informed about CLK electric seats. My wife has a V reg CLK 320 Elegance. The drivers seat is very slow to move forward and back and only works with the memory button not the icon. Is it easy to lubricate the seat slides and motor as the latter seams to be struggling. Obliged for your input
