The main problem I ran into was
- Parts that were marked as compatible that were absolute rubbish. You would there is little difference between one brand of wiper arm and another. Apparently not!
- It takes 2 days to order a part from the internet. The nearest part supplier is a 30-40 mile drive. So if you forget to order a part you are either waiting another 2 days or you have a 2 hour drive.
As a result. I ended up rebuying all the parts about 2 times and I should have gone to a local parts dealer where they give you either Genuine, OEM or quality aftermarket. The thing is that I compared the genuine parts that did work with the ones I bought from ebay and visually there is little difference. So now I only buy Genuine, OEM or quality aftermarket.
It is all part of the learning experience. Even though at the time it was frustrating.
