Electric Window Problems on a C70

AlisN1dlan »

2000 C70 (have no idea what a “trim level” is) 58K miles.

Very shortly after the warranty expired my driver’s side window refused to come up in the middle of an icestorm. I’m an hour away from the nearest Volvo dealership and my son had his street rod in my garage so I took it to a local repair place that advertised they “worked on all models”.

After a VERY short look-see, they came out and told me I needed a “window regulator” and that since it was a part only available from Volvo, the price for the part alone would be $880. The total bill came to over $1,000 but I really had little choice.

After they “fixed” the window, it began leaking terribly. They tried twice to fix it but couldn’t – and since the car was hesitating like crazy by now – kind of like it had water in the gas tank or was running out of gas – I took it down to Volvo. This was, I think, in February or March of this year.

From an electrical point of view it sounds to me that the switches have taken in water and therefore damaged them. This obviously causing the windows to fail.

The last resort is that for some reason your door window seals are damaged and the motors in the doors have taken on too much water , again causing damage.. However i wouldn’t of thought that this would be the case. It is more likely to be the switches.

Maybe remove the switch panel from the car and attempt to split the unit to dry them out and give the inside a good clean with some electrical contact cleaner.

I also have a 2000 C70, love my car, but now the drivers side window does not roll up ! It will roll down, but not up, I do not want to pay what the dealers are charging! Does anyone know if I can find this part ( was told it was the relay switch) ?? And If so where and approx how much, I heard it was easy to install, just snapping in? Is that true? Any help would be appreciated also how important are the Oxygen sensors?? Thanks !!!!

You probably have a bad switch in the driver’s door. It’s a common problem for the contacts to wear out. Unfortunately that master switch is rather pricey. There was a thread in here somewhere about someone taking theirs apart and fixing it.

Yes, the oxygen sensors are very important, but have nothing to do with the window. Are you having a problem with them?

Here is a picture of the culprit, as you can see, there is quite a bit of build-up under the “up” contact (Fourth from the top). Quick fix for about 15 minutes tops, no wonder these dealerships make a fortune on switches this way!
