BronsonA2150 Posted 16 hours ago Share Posted 16 hours ago Truck will sit in a rain storm and when you get in it to move it water will run out from behind dash/computer somewhere pictured and across floor. Is there a common spot for these cabs or firewalls to leak?

880joe Posted 10 hours ago Share Posted 10 hours ago Air horn or cab light gaskets windshield rubber would all be a good place to check 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75849-94-ch613-water-getting-in-behind-dash/#findComment-580632 Share on other sites More sharing options...
Mark T Posted 8 hours ago Share Posted 8 hours ago They like to rot under the plastic part where the wipers come through from the cowl too. '94 ??? lots of places it could be coming in. need to make friends with someone and start watching while running the garden hose on different places.

BronsonA2150 Posted 5 hours ago Author Share Posted 5 hours ago Well I think I just found my issue trying to fix a wiper bracket. There’s water standing down in this shell just under the hvac intake. Guessing it’s overfilling during a rain and overflowing into where it attaches to firewall. So is there a drain somewhere for this?
