I have a few rain leaks somewhere that I haven't yet identified. More concerning to me though is that i hear water sloshing around in the subfloor for several days after a hard rain, but I haven't figured out how to drain it. Has anyone else experienced this and if so where are the drain holes? I'm sure I just have some drainage holes/lines clogged up somewhere but not sure where to look first.
there are small slits above the pinch welds of the rocker panels. one just behind the front fender and one just before the rear fender. Wiggle a good sized zip tie in the slit and water should come streaming out. Hope that helps.

good suggestions above. i had the same problem but the zip tie trick didnt work for me. It may have been because my 80 was parked on an incline and the water had sloshed to the front corner of the rockers. Anyway, i removed the two front-most rubber plugs on the bottom of the rockers and got about a quart of water to drain out.
there are some larger black plugs on the bottom of the rocker panel itself that'll drain the water even faster, but what you've done cleaning out those drain slits is the long term solution.
Ha, i just got the same thing, cleared the seam holes and waters been running for quite awhile. Great source of gray water...yeah right, But I was wondering if this is a drivers side only occurance? Just wanting to make sure.
As above, it's a small slit on the inboard side of the pinch weld seam. Three each rocker.
In the past, I've used a large-ish flat blade screw driver, and punch it vertically up into the slit with a hammer so the slit becomes a 1/4 round slit/hole
Anyone have a picture or diagram on where they make a punch hole in the slit? I also have water sloshing on my 92 and got some drained out from those grommet opening.
Slits are where the red zip tie is sticking in (photo taken from MUD) and are along the pinchweld on each rocker. You could widen the slits with a screwdriver but you risk scratching paint to bare metal in an area that is often wet. If the slits along the rockers are cleaned out, the water will drain.
I roll with the front most plugs out. I have the openings POR15ed and I have tons of oil and fluid film pumped into my rockers with no noticeable problems.
Right, sunroof drains. Thank you. front ones for sure at least, I think rears end up behind rear wheel? It's been a bit since I was inside either rear quarter area.
I had front driver soaked floor due to sunroof drain (rocker slit was clogged), front passenger damp floor due to bottom corner windshield leak, and then I found a few small rust holes in the roof under the paint. Was getting wet near the rearmost passenger grab handle, down the rear pillar and onto the rear corner floor. I found the holes after grinding a little rust spot on the roof that I was simply intending to repaint, and then I did the same wherever the paint was split, found 4 or 5. Took care of all 3 individual issues and not a drop has made it inside since. Resealed windshield, cleared rocker drains and relocated hoses through floor plugs, grind/bondo/paint roof spots
@SpenserAK is right, the long term solution is to reroute those sunroof drains through the floor. They should never have been routed into the rocker panels.
@tone33, if you have the opportunity to remove your dash (it isn't a big job, really), you can verify whether you have a windshield leak or not. If you do, you'll see rust stains on the inside firewall surface, especially where the reinforcement tubes bolt onto the body (you'll see it when you remove the dash). Any moisture near the rear grab handles is due to the rear sunroof drains; they're most likely loose at the pan connection, although I've never seen these leak personally.
Thread revival indeed!! My leaks come from clogged sunroof drains, and sometimes from the AC condenser under the passenger dash. I re-sealed my window at some point to prevent that as well. And yes the rear sunroof drains flows into the rear quarter panels. One of mine had deteriorated over time and i sleeved it with a slightly larger plastic hose. Always something leaking in these old trucks!
