z4 convertible issue and wiper blades

[z4suni]

Hi,

I have a 2003 z4, my top does not go down and my wiper blades do not work! Does any one have an idea as to why? Is it something I can fix myself? if not, would any one with experience know why this is caused and how much it would cost to get it fixed?

Thank you!

Sounds like two separate issues to me.

For the convertible top problem, open the trunk and check to make sure the partition is down- i.e. less trunk space. If that's not the problem, then the hydraulic pump motor is probably full of water and is shorted/corroded. Pretty common problem. The entire top has to be removed from the vehicle to replaced the hydro pump. Removal of the top is a two man job. The vehicle's paint can be easily damaged if you're not careful. I work at dealer and I only trust a few guys I work with to help me remove a top. I would not recommend this job for a novice.

Hard to say about the wipers. Any good with electrical?

It would depend on your problem. I had something like this happen too and it was because of faulty wipers. I got mine off a scrapyard along with lots of wiper blades. I guess that taught me to buy legit ones instead >.>
