Well after much searching I think I have found my leak. Thought it was from the new windsheild I had installed but it appears to be coming from the heater box where it it joined together with those clips. I The one clip where the leak is was rusted out so I put on a new and made sure the drain was not obstruced. I flushed out the box with air and then some water to ensure it was clear. i thought this would take care of it but it is still leaking from this seam. It drips on to the hump and goes down to the drivers side floor pan. I an certin this is consendation from the A/C unit. It is in a very hard place to access. To get the clip on I had to put it on the end of a long screw driver with same tape and press it on. I think if I remove the radio (mounted in the lower space in the dash) I may be able to put some silicon on the seam. Has anyone experienced this situation or have any ideas on how to repair short of removing the heater box? Any suggestions appriciated.

Thanks Steve
