[drzen99]

My 86 - 4door Corolla Hatchback has a leak somewhere??The passenger side/front carpet and floor pan are wet after driving in the rain??Anyone had the problem and solved it? Thanks. ~ dale

that sounds like your heater core is gone.... but i would check and see if your floor pan is rusted

Not losing any water so can`t be the heater core,and caulked and undercoated the floor pan and there is very little rust anywhere on this old Corolla,but thanks for the input. ~ dale

Have you checked your cowl under the windshield? Do you have a sunroof? The drain tube might be clogged and leaking out to there. (Not to familiar with the AE82 here)

I would be inclined to think your cowl is plugged up and leaking back into the car... As long as you don't have a sunroof!! Keep us posted

The floor pan was bent upwards.Probably from hitting some object.Used a 2x4 and whacked it down and straight(er),and sealed all the spaces with silicon caulk....when the caulk had set,I sprayed it all with a can of undercoating from NAPA.We had rain from Hell for 2 weeks and so far so good.NO LEAKS.....Thanks to all for the suggestions tho..it always helps to get input from other Toyota buffs....Mine has 260,000 miles and purrs like a kitten.Valve seals stopped the smoking and plugs,wires,filters,etc. has made it run like a sewing machine.I`m lovin it.....My 76 Chevy,350 4wd pickup gets 10 mpg.....My Corolla gets 30 in town and 30+ on the road with a 5 speed.....also replaced tie rods and CV joints and had it aligned,and brakes all around....Paid for, no car payment,$114 for 6 months insurance and great milage.WHo could ask for more????
