How do you replace a turn signal flasher for a 1996 Cadillac DeVille?
Find it, remove (or just lower) the under-dash lower panel by removing 2 screws. The cube-shaper flasher is clipped to the inside of the upper panel left of the steering wheel, and is plugged into a harness of several wires bundled into one cable. You will probably need to locate it by feel -it may help to activate the turn signal if either direction is working, the click will help you locate the flasher by feel. Remove it and take it to an auto parts store for a replacement unit - Autozone (just for example) has it in stock at all stores, not even in the back room. Plug in the new flasher from where you removed the bad one. You probably won't be able to clip it back where it was, just stuff it up in there and replace the panel.
I have a 99 deville with the same problem. Two mechanics have told me it is the HVAC vent motor that has gone bad. Basically the motor that controls the vent doors is out. One quote I got was $1100 to repair it. THey have to remove the dash to get to the motor. Hope this helps. replace the heater core! sounds dumb right? but the heater core has the in and out on the same end of the core and the fluid travels in a u shape in the core it looses heat in the first half of core before it travels in the end tank to the other side of core and back out. The air plenum has a divider in it all the way from core to outlets and core heats passenger side first. The core gets partly cloged by the coolant sealant supplement (stop leak) that GM uses in all these engines. result? not enough water flow for the water to stay hot traveling through the whole core.

How do you install a water pump in a 3.5 liter engine on a 1994 Concorde?
you need to take the front of the engine apart it runs off your timing belt. Don't remove the fans just the alt/power steering belt. Then take all the front cover bolts out except the lower two on each side of the crank pulley just loosen those. Remove the cover.
Don't remove the timing belt just line up your timing marks on both cams by turning the crank pulley and use two vice grips to hold them in place. Put the grips on top of the front cover to the inside of the cam sprocket's, not to tight just enough to hold them in place. Now you can remove your water pump bolts and flip the pump out leaving the belt in place. To install just reverse what you just did.

Where is the fuse or relay located for power seats in a 98 cadillac deville?

How do you change the radio in a 1999 Cadillac deville?
OK, I changed the radio on mine and it was the worst thing to do. After I put the after market radio in the car, it started to act up. The a/c wouldn't cool and sometime the car wouldn't unlock with the remote, I would have to do it manually. I asked around and it ends up that the original radio is like the heart of the car and there isn't a module to substitute it. From experience don't change it.

How do you replace thermostat in 1998 cadillac deville?
* Drain some coolant into a clean container until the coolant level is below the thermostat housing. * Remove the upper radiator hose connection from the thermostat housing. * Loosen the housing bolts and remove the housing. * Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing. * Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings. * The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block. * When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat. * Install the gasket. * Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks. * When the engine has reached operating temperature make sure the thermostat opens. * You should be able to see coolant circulating within the radiator. * Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up. * If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced. NOTE
When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.
