So as it says, i have a 95' Celica convertible, and it has a problem. The drivers side quarter window doesn't go up right. At first I thought it just was getting caught so I took a quick look and no luck, so we brought it to a local mechanic, a good one, and he takes it apart before I completely agreed to, and ended up paying $95. He says, well the motor and regulator are shot and need to be replaced. He quoted us $726 total. I was like no way. I took it home, took it apart myself and guess what. The motor was fine, but since the window kept going up I figured it was the regulator, which was 95.29 at Partznet. It came today and I was home early so I just looked at my self. Well I figured out that one of the guide wheels broke off, and was causing all the problems. So it is 1.52 on Partznet. Yipee!! this is the second time I've fixed things my self and saved a total of 1050 so far. Me gusta. Now here is the problem. I got the window out, and I need to take the plate off but I'm not sure which tool I need for it. Here are the Pics.
