1) My suggestion is to get the window at a junk yard or someone parting out a car. A Lesabre 4 door should fit too.

2) Advance Auto (and other parts stores) will pull the codes for free. Find out what the computer is complaining about and fix that problem. If your car needs a tune up, then by all means do it but don't just throw parts at it in hopes of curing the check engine light.

3) That's a pretty popular problem. I have 3 clusters and not one has a functioning compass or DIC... although I think the problem is in the DIC module rather then the displays. One of these days, I'll get around to bench testing all of the parts I have to try to make sense of it.

4) That's a bit odd. The SSE trim level and the C engine came out in 88 not in 87. Nevertheless, there are no real "common" mechanical problems with this drive train. I've heard of several owners with over 300k miles. The trans doesn't have quite the lifespan as the engine but can be rebuilt reasonably.

The Teves antilock system is an expensive nightmare.

Check for rusted fuel & brake lines near the fuel filter

The rear door latches have a bad habit of rusting. This causes the rear doors to not open
