might be behind the glove box or under hood on firewall

There is a fuse and or a relay you need to be looking for. Also for the fuse to be blown something has had to have shorted out. It could have been water causing the short or you have a bad wire somewhere grounding out.

There is a fuse at the passenger side footboard that has blown. Sitting in the seat, your toes point to the panel that needs to be removed (bottom of glove box facing down). There should be a 15a fuse in there that has blown. Replace it last. First you need to find the short behind the radio and a/c control panel. Sometimes they are difficult to find but look carefully around areas where the wire harness has been near a sharp corner or surface. You should find it in there. If not, the short is located in the main harness near the fuse panel. I wouldn't advise going in there, you should just take it to an automotive electrical specialist if you cannot find it because you will pull your own hair out trying to find it and it really isn't something that I can easily tell you how to do. Those starting points should help you out though and Good Luck!

on the right side of steering colum there is a plug. there is a wire that gets warm and loses connection. check by moving plug. my heater and ac would not work and caused the vacume swith to stay open.

What part? Can you describe it? Or give a location?

To be sure its the pump spray some starting fluid into the intake and try and start it.If starts runs for a few than dies most likely the fuel pump..You can also after doing that have someone crank car over and beat on the gas tank and usually if the pump goes bad you can get it to work by hitting the tank while someone is cranking it...Its not a permanent fix but will answer you questions...

The Oldsmobile and other makes with electronic control board's are plagued with problems. Call your local auto recyclers and get a replacement switch. As far as changing the switch once out of the dash it is just a matter of disconnecting it and hooking up the new one, fairly straight forward . You may need a torques screwdriver to remove it from the dash. Mike

I would start at the fuse. Does the blower motor turn off when the fuse is pulled? A relay is usually used in this circuit and can sometimes "stick" allowing the blower motor to receive constant power. A quick check to see if it is a wiring problem, switch or the relay its self would be to find the blower fan relay and see if there is another one of the value you can swap with it. If the problem goes away, chances are it is the relay but I always like to take a volt/ amp reading to double check my work.

check your alternator - this is more than likely the cause. advanced auto or oreily's should be able to check this for free.

if that isn't the issue - you probably have a bad ground in your electrical system. could be expensive.

It sounds like the fuel filter is either plugged or the pump is failing, there is also a possiable problem with the Mass Air Flow Meter located in the rubber intake hose, make sure these hoses are ok, and have no cracks or clamp leaks, this allows air to bypass the meter and will make the engine have a severe hesitation off idle.

Nothing specific as engine number is not disclosed but; Typical plug sites are in the side of the block under a manifold ; at the back, inside or above the clutch housing - awkwardly near the bulkhead; and in the top of the cylinder head, often hidden under an overhead camshaft . Plugs can blow out completely, resulting in a sudden loss of coolant.

Check it by using your hazard lights. If they flash, the relay is OK and you have a woring issue.

Does the service engine stay on after you have restarted the vehicle? If so connect a scanner to see what codes come up. Could be as simple as an idle adjustment.
