1988 chevy truck w/tilt steering

This can be found in the Hanes repair manual that you can get at any auto parts store, Auto Zone, step by step with photos. Not a hard job but you will new a steering wheel puller to get the lock ring out and the wheel off.

I own a 1988 gmc c1500, the electric fan behind the rad is on constantly from the second i turn the key on until i shut it off. Wondering what may be causing this?

The fan is activated by the temperature sender and turns on when it reaches a preset temperature. Yours may be faulty so switches on at a low temperature so it needs replacing (the sender not the fan). It is also possible that there is a wiring problem and the switch has somehow short circuited so is permanently live, meaning when you turn the key the fan starts. If it has always done this, then it is also possible that a previous owner has done the short circuit, something I have done in the past but I put it through a switch that you activate when in traffic and the air flow is low. It might be worth tracing the wires from the sender to see if there is a switch somewhere in the cab.

Fuse panel under dashboard. 2 empty spaces on the right side of the panel that look like they are for relays or breakers. What are they for?

I was told that they could be used to store extra fuses in case one burnt out. If you add something you could maybe use to wire it in.

I replaced my oil with pure synthetic.Now I only have oil pressure when the engine is cold.

Perhaps. Please go in very soon to a good honest shop and have your oil pressure tested with a meter. If it is really bad, go back to regular oil.

4 wheel drive will not engage

Depending on the model by production date. Some have hub that you have to lock in. The newer version the lock in was done in the front differential. There is a n electric plunger that locks in the 4 wheel drive. There is a harness that goes to it, check the harness to insure it is not damaged. there is a brown wire that ties back to the transmission that must be hook up for it to work properly. Last but most forgotten is you must back up to fully engage the 4 wheel drive. Hope this helps.

Can I get a manual window door from the salvage yard and replace the power windor door on my 1988 chevy c1500 that doesnt work?

Yes, you can get a Manuel operated window and install it in your present door you just have to disconnect and remove the present window motor and the elec. You may have to change the door pad as well so you have a hole in the panel for the manual crank for the window.

No pwr in pass front dr sw n why two same sw on pass side dr

You need to check for a blown fuse and any broken wire on the passenger side and if you do not find any you will need to remove the door panel an probably replace the switch. The reason there is a sw on the driver side for both doors is so the driver doesn't have to reach over to operate the passenger side from his position. I hope I understood you question correctly.
