hi folks - another question about my 'new to me' 94 850 wagon - the carpet in the front driver and passenger wheel wells appears to be getting wet - it seems that it is connected to rain and is definitely not coolant from the heater core - the main air dam drain at the firewall was plugged and now cleared, the sunroof appears to be draining as designed - this is my first 850 and i've never had this trouble with my '90 740 so am a bit stuck as to what else to check, any suggestions???

ps. the previous owner installed rain gutters from a v70 (i think), i assume he did this to avoid the 'rain in the window' problem that i've read about with the 850's - could these be contributing to my problem or are there drains in that channel that i should be cleaning out???
