The factory radios usually have 4 small holes. Two on either side of the front radio panel. There is a tool that you can get from a parts store for just a couple of bucks that you insert into the for holes at the same time.(There are two U shaped tools, one for each side) When you push them in it will release the pin holds and you can slide out the radio.

drl module defective

check if you car has a cut out system

If the battery check out as fully charged, remove the connections, clean the battery posts, reinstall the cables and retry. If the clicking continues, the chances are that the starter solenoid is not engaging. Generally, you are better off replacing the starter and the solenoid as a unit. Your starting problems should be solved.
Let me know if you have any other questions. Thanks.

You can get a "Chilton" book that will show everything for your vehicle or try googling "1984 Buick Riviera belt diagram" and there may be a site that has it posted.

No, you do not need to remove the torque axle bolt to replace the serpentine belt on your 1995 Buick Riviera Supercharged Series 1. However, you may need to use a serpentine belt tool to relieve tension on the belt before you can remove it.
