Why is the electric seat backrest of the Tiguan not responding up and down?

[OAlana]

Possible faults causing the malfunction of the Volkswagen Tiguan seat adjustment include: 1. Electric seat jamming or seizing, mostly due to oxidation or insufficient lubrication of the seat adjustment linkage. 2. Sudden seat failure, where it stops working properly, is generally caused by wiring issues. Check if the fuse is faulty, then inspect whether the seat motor is functioning normally. Wiring problems require repair at a 4S shop. 3. Sometimes the seat does not move fully during use, which is usually caused by blockage or lack of lubrication in the adjustment linkage or slide rails, leading to jamming and incomplete movement.
