The thing I am wondering is about water damage. Was the vehicle ever in a flood? If not I would look for another radio in a salvage yard. The age of the unit is a major consideration and it is probably failing due to heat, stress and vibration.

The fuse you are looking for is located in the engine compartment, center left (driver's side). remove the square (approximately 8" by 8") black plastic cover to expose the fuses. The fuse that controls both the windows and the seats is the 50 amp square fuse at top center (top is @ engine side, bottom is @ fender). You will no doubt notice that the fuse element has burned out by looking thru the clear plastic window on the top of the fuse and comparing with the 30 amp fuses to the right of this fuse. If your windows are operating, but your seats are not, your 30 amp rectangular aluminum covered fuse under the instrument console left of the steering column needs to be replaced (remove the fuse block cover by unscrewing the plastic hex bolt in the center of the cover and releasing the plastic overlap catches on either side of the cover). Fuse layout legends are printed on the inside of all fuse box covers.

I'm not sure why you want to change the oil again. Your oil pressure numbers appear to be normal. Replace the oil cap if it's bad. You'll have to scan the ECM for codes to find out why the the check engine light comes on.

What is wrong with the transmission, this is a manual transmission correct?
