In all the rain we've been having, the driver's side of my '91 wagon has gotten soaked. Is there any particular place I should expect water could be coming in.

 

the bottem of the windshield weather striping is usually a trouble spot also the rubber gaskit that leads from the engine through your firewall into the cabin its under the carpet by the pedals. or it could be the weather striping on the doors. the only other thing i can think of is the water tube for the sun roof or theres a rust hole on your floor pan somewhere.

 

Thanks. Saturday I replaced the weather sealing material under the valence and vacuumed and washed the sheet metal underneath. I figured doing one improvement at a time would allow me to isolate the problem.
But is there a weep hole for water getting past the seal to exit the area in front of the windshield?

 

Replace the weather stripping/rubber seal around the windshield.

 

I sprayed an "overcoat" around the windshield then did the same thing on the channels on either side of the roof but water still gets in. My daughter tells me she had the windshield removed and the seal renewed. So now I can't figure out where the leak could be, but it gets soaked when not in motion.
