I am replacing the rear speakers on my 98 single cab silverado...

I just need to know how to remove those panels so I can get to it

should be the same as my 01:
remove the mirror cover panel(tirangular panel above door panel) by popping out the two clips on the front and then lifting up

pop off the handle cover
pop out the light and pull out the plug and bulb
pop out the lock slide so it soes not get hooked on the pin when you lift up on the panel
pry up and remove the assembly for the window and lock switches
unplug the lock and window plug
there are two screws you need to remove
one is behind the window and lock switch assembly
the other is right on the other side of the handle isvisable
press in and lift up the panel and it will lift up a couple inches then you can remove it- it takes a little pressure
to install rest the lower tabs on the highest notch, this aligns the other clips, then lower into place

Nah...totally different to the 01.
Here's how to do it. (this is a 'how to' I put together for another forum on replacing door handles).

Changing door handles on an OBS (98) Suburban.
Start with removal of the interior door trim and panel.
Firmly pull the triangle piece (plastic piece covering the back of the mirror mounting screws) until it releases. It’s very tight and requires quite a bit of force.
Once released a little it can be slid up and off.

Remove the two Phillips head screws located in the armrest.

Remove the switch panel/speaker by lifting the rear section straight up until the clips are free. Slide the switch panel backward until the front tab is clear and remove the panel and disconnect the plugs going to the speaker and switches.

Remove the door handle bezel.
Use a small screwdriver to put pressure on the bezel as you slide a bigger, flat bladed screwdriver between the bezel and handle assembly at the tree points shown in the pictures.

After the three clips have ‘popped’ releasing the rear section of the bezel, gently push the bezel forward to release the front clip/tab.

Work your fingers under one corner of the door trim and pull firmly.
Keep working your way around pulling in the area’s where you can feel the trim is fixed to the door. Get as close to the fixing plugs as possible and pull HARD!
You may break a couple of fixing plugs in this process so it’s advisable to buy some spares before undertaking this process.

Once all of the fixing plugs have been released, the door trim can be lifted up and away from the door. The top of the trim hooks down over the top of the door between the top of the door and the window glass.

Should anyone have pictures of removing rear interior panels of cargo area, I would really love to see them. The ones removing the door panels are great.
Thanks

Great post hquick, but I think he is talking about the covers on the rear pillars.

Great tutorial so far... I have gotten as far as posted but am now faced with a pretty securely attached door latch mechanism...Any advice on how to proceed from there. See below...

OK, drilled out the rivet. SLid the old part out ...slid the new one in and put in an aluminum rivet. Pretty simple once done.

I think the Al rivet will work rather than a metal screw. Doesnt seem to be a lot of stress on the rivet.

We'll see, if it doesn't should be very simple now.

thanks Howard for your pictorial, it was the most helpful thing I found.

It should be fine. I would have screwed it back down because knowing me, I would have left something unhooked and had to go back it there after it.

DUDE. . . so far the best info on the web. I have been struggling w/it for two hours. . . will let you know how it worked. 3 seconds later POP right off!
I cant say thank you enought for taking your time to post this for the rest of us morons out here.
THANK YOU!
Big Dave
