Dash replacement

I’d agree, it takes maybe five or ten minutes to unbolt the box once the dash is out which itself takes maybe an hour or two. You can then replace the dampers which are probably leaking air by now and have a decent system by 90s standards at least.

Here’s a link to a dash replacement when I did my 98, maybe it will help. My two cents: pull the dash and it’ll be easier than cutting the box apart and trying to re-seal it.

Dash removal and replacement

I replaced the dash in my 1998 K1500 and thought I'd post a how-to. The steps below are from alldatadiy.com which, I think, mimics the factory service manual. I've added pictures to relevant parts as some of the steps are a little vague. I'd really recommend getting a box of ziploc bags and...

Yeah either way I think I'm going to need several days to take it off the road and I'd prefer to clean it out.

Yeah, pretty sure it is riveted to the dash plastic. The dash can be removed without popping the rivets off and leaving the bar in place attached to the dash.

That connector, C271, is for roof lamps, automatic day/night rearview mirror with compass, and sunshade mirror lamps.

Service manual refers to the connector's location as "IP harness to Roof Lamp & Mirror harness".

The mating connector would be along the firewall after coming down from the driver's side A-pillar.

If you don't have the mating connector along the firewall, the just leave the dash connector unplugged.
