I recently found water leaking from under the dash on a 122 via a new (to me) route. Water was coming in where the outside clips hold down the heater air intake screen. The inside clips poke through holes into the air intake/heater box and on to the drain - hopefully. The two outer holes drained onto the firewall, then on to several holes in the firewall that should have been plugged but weren't.

I used some "Mobile Home Putty Tape" to plug the holes around the clips. Tested it by blasting the windshield/wiper arm area with a hose. Problem solved!

I originally bought the "Putty Tape" locally at a True Value hardware store to repair my truck camper. It stays pliable under a wide range of temperatures and sticks pretty well, too. I will probably try it on the holes where the chrome trim fastens through the body.
