OK, about the damage. It involved two major parts- the skirt, or as Chrysler calls it “Cladding” and the underbody shield.
Many clips holding the skirt were broken and it had a deep scratches on the bottom.
When I looked up the parts fiche I found only the skirt, but no clips. The worst case scenario would be that the clips weren’t sold separately and/or the clips attachment points on the skirt were broken. I jacked the van up and took the skirt off. It wasn’t bad. Several clips were on stands and those stands were partially torn- nothing that couldn’t be fixed with epoxy.
Everything else looked good. The metal was untouched. I took a pair of clips and went to the dealer. Their parts fiche showed them as available, and they had them in stock. Also bought a plastic epoxy from Home Depot. $20 for everything.
Back home I heated the torn stand with a heat gun- it may help to return the plastic to its original shape and epoxied the stands back in place.
Let it dry, installed the clips- there were about 20 of them- and skirt snapped back in place with minimal troubles. It is still just a bit off- the plastic in the stands stretched and the heat gun couldn’t fix it. This is still better than having to purchase a new skirt and have it painted. Not only it would be more expensive, I don’t believe that a body shop paint job can match factory in its quality. Even if Criswell agreed to repair the damage I would ask them to save and reuse the original part. I left untreated the scratches on the bottom. They aren’t visible and it is not like the skirt is going to rust. I'd prefer to have this spot sanded and painted though.
Next I went to work on the shield. I found a surface scratch on the metal above the shield, covered it with a metallic tape to prevent corrosion. The shield itself is made from a thick felt like material. (The large black part in front is the door kick sensor.)
I tried to remove the creases with steam. It helped, but the rip still couldn’t be completely closed off.
I repaired it with staples and duct tape, which may hold for a while. Ultimately the shield will need to be replaced in a shop. I’m not going to crawl under the van.
Fixing the damage is simple and not expensive. That shield is $160 online with free shipping, the dealer cost has to be under $100. It makes me wonder even more why Criswell flat out refused to help me. I didn’t come in screaming and demanding a replacement van. We could come to a reasonable solution.
