Just rinse with a fine spray, not a heavy stream. And put a couple towels down in the passenger footwell. Have a helper watch and yell if necessary. Shouldn't be a big deal at that point.
With dual air, and not knowing your routing, you might want to towel both sides.
Keep in mind I don't think either of your cars should be bad enough to notice a difference yet. The 98 MAYBE, especially if you park around alot of trees.

EVAP core = evaporator core.
Well, the usual cause of cloged EVAP cores is pollen and mold. So just parking under trees is not neccisarily a cause. There is no air flow to draw this in when parked.
Daily driving through a streach of highway that has a lot of pollen floating around can cause the EVAP core to plug.
GM studies showed that a great way to prevent the EVAP core from plugging is to "blow dry" the core before shutting the car off.
If running the A/C, you should turn the compressor off about ten minutes before you get to your destination but leave the fan on high. This will help to dry the core.
A core set to sleep when wet is what promotes mold and clogging.

Now you see why I made the comment?

Well, it sure was nasty. Lots of pine needles, seeds, and pollen. Emptied half a can of brake clean and sprayed it down with the hose. Got a little water in the passenger area but I had a towel ready on both sides. After putting it all back together I ran the defog first to dry the box. When I turned the lower and upper on no water came out. Now the bad news. It made little to no difference. I'll say it blows maybe 2% better then before. So I must have a blockage somewhere else.

Let'* pull your blower motor next and take a look in there. We occasionally see buildup/nests in that housing.
You got all that debris out, including the needles? Do you have an ECC or manual?

Yep, took all the debris out with forceps. I'm thinking you're right that there is a blockage between the blower motor and heater box. It has to be. There is no way anything can get between the evap core and the tributaries leading to the vents, is there? Yes, I do have a manual and I think it has a pretty good explanation of taking the the blower out.
