The original Volvo window regulator sliding pivot blocks are made of plastic. They work great while the car is new and a few years after. As your Volvo gets older, many window gaskets and guides are not as pliable, they dry up. The plastic slide of the window lifting mechanism that attached glass to the window regulator is having difficulties supporting its intended function. Metal clip for pivot attachment breaks away tiny ears of the plastic slide that is holding the clip in its place. Resulting in the window falling inside the door. The situation can also cause an even worse scenario if we attempt to FIX the window by operating the power window switch. As a rule, that can cause all sorts of damage to the window regulator.
Replacing broken plastic part with another plastic part does not solve the problem. In many cases the repair does not last but for couple of UP -DOWN window runs.
To solve the popular issue - we came up with the solution - we made stainless steel replacement slide blocks, and we had them coated with Teflon.
They perform very well in any temperature and stay in place. If you are looking at this page - we are certain that you replaced a few plastic slides already and do understand the advantage of metal parts versus plastic.
