So I was replacing my front upper control arms on the 2011 XJL and disconnected the wiring harnesses from the fuse block for better access. I thought I put them all back in the correct spot but now my windshield wipers are not working. I assumed (maybe incorrectly) that they would only fit back on the correct connector. Does anyone have experience with this? How big of a problem did I create here?

 

Can you post any pictures?
Maybe someone with the same car can compare what's different?

How was the drivers side upper rear bolts?
That was very difficult for me.

That's how I got myself in trouble. I took the fuse box lose so that I could get access to that bolt. It came lose real easy after I got in. Did you have to remove the strut? The T60 bolt on the bottom of my strut is completely frozen. I can't get that bolt out.

 

Okay, I figured it out. I missed one of the connectors under the fuse block. WHOOPS

 

Glad to hear it!!
I just struggled and finally after a long time got it out and back in.
Yes I had the strut out.
But it was a huge pain!

Yeah, it's a huge pain but saved a lot of money. I got a quote from the dealership for $1,700
