The front defogger actuator not working. The blower is powerful. The lever moves left to right just fine. When lever moved all the way to the left, the air does not blow onto the front windsield. What are the disassembly steps/instructions to get to the parts attached to the actuator lever?

I searched but cannot find this subject in this forum. Thank you for your advice in advance.

Look up the heater controls in the FSM. One of the maintenance items is periodic lubrication of the cables and pivot points for the diversion valve. Despite being able to move the lever, you may have a broken solid-core cable. Pull the radio console and look behind the right hand side, careful not to break your radio faceplate.

Those are great suggestions. I now have the FSM for the heater. How difficult is it to repair/replace a broken cable if that is the problem?

Good morning, I had the same issue, prior to pulling the controls (PIA), crawl under drivers side, remove the duct that crosses under the steering wheel area (two phillips screws). Take a flashlight and look toward the center of the vehicle, there is a white pivot assy that controls the air flow, while moving the cable to defrost, watch the white pivot assy, it should move to where there is a notch in the assy. Mine wouldn't go past this notch (to defrost), I had to clean years of goop off the pivot assy and lube, while lubricating I continued to slide the selection lever back and fourth. After about ten minutes, it would going into each selection position with out issue.

I was going to pull the cable selection assy from the dash to review until I looked under the dash from the drivers side. Easy to clean and this might resolve issue, if the cable is broken, it is easy to change without removing the lever assy from dash (this one cable). There is a salvage yard in Springfield MO (Buddys U-Pull) that could have the cable, I have been buying several parts for my 1990 LWB from them and so far they have had all items requested.
