John,

I reckon the critters carry it in through the A/C outlets and wind up making
their nests there.

Re the foam - IIRC JimB had some thin white colored Styrofoam sheet that was
used to package parts.

Going through the system end to end sounds like a damn good idea to me!
Hopefully you will be good to go for the whole summer!

Regards,
Rob M.

Charlie - I got the front cover off. The two cores look very clean from the
front. Beats me how that stuff gets in behind there...

John H - I had to remove all that you noted. I didn't realize the bottom
would come off, but it did.

Rob - Yes, the doubler was there, and slightly bent DOWN in the middle. If
the holes are centered, I'll just replace it with the crown up - good
advice! And it looks like there is/was a foam strip all around the
circumference of the evaporator on the inside of that bottom cover. Now all
I have to do is find replacement foam for the doors, etc - boy, that old
foam stuff is nasty!

Dennis - thanks for the link. I have seen those before, but couldn't find
them today. The ones I saw this week were of the resistors removed, and
looking like what I found today. I really hate to tear into it any more, but
I know I should as long as I'm this far. Now that the bottom is off, I'll
look tomorrow with a mirror at the back side of the evap and see what's
there. Because I posted a few days ago about the a/c system cycling on and
off every 20 seconds (low on Duracool), maybe it's just a good time to look
at it all and replace the things idrob did.

Thanks for all the comments and advice

Shot
