suspect a bad cabin compartment selector or actuator, got to look under dashboard panel.

slide the seat forward and look at the rails in the back.

I'm not positive about the DeVille, but I've removed seats from lots of other vehicles, and some of that may translate over here. There should be four bolts (studs, really) going down through the floor from the seat mount frame. You should be able to find the four nuts under the vehicle's floor pan, after you jack up the driver's side and put jack stands under it (if it falls, it WILL crush you to death). Loosen those four nuts but don't remove them. Now back inside, feel underneath the seat - find all the electrical connectors. Unplug them ALL. Doublecheck, triplecheck, make sure you get them ALL. NOW you can remove the four nuts underneath the vehicle, tip the seat rearward to verify that you got ALL the electrical connectors, and remove it. It's HEAVY.

It is under the passenger dash. You have to take the cover off the bottom next to the floor board. Then there re about 5-6 screws around it. It's big.

buy a haynes manual for that model--partstore or online----or send this issue to magicmechanic -his site has a library of auto tips but he will reply w a practical answer--hes a mastertech in any make

On the side of the intake manifold follow the plastic vent line from the canister to the intake manifold. It usually is within a few inches of the test port which has a green cover on it.

You may have a torque converter not locking. At low engine load conditions at hwy speeds to save gas the engine computer will tell the trans to lock the converter which results in lower rpm. Either the TCC solenoid is not locking the converter, or the PCM has failed and not sending signal to the TCC solenoid. If this has been going on over a week, im willing to bet the PCM has failed, otherwise a good one should catch the TCC if its not working and should throw a code. Its my best guess with no tools to know for sure. Good luck :)

I would say the simplest thing to do would be to stop by an auto audio shop and he could print you a copy off...because in order for them to install an aftermarket radio they have to by.pass the factory amp and they need that diagram to do so...and Google the cadillac form that also might be a good lead

You may need to replace the abs computer.
