any direction on how to get into this area and "unplug" the drain holes?
HELP....cab getting very wet here in OREGON! |
What's the weather like there? Warm or cold? A lot of rain maybe?
It could be that the condensate drain is blocked. If you run the climate controls in any setting except vent or maybe heat, the A/C compressor runs, even if you have the heat turned up. The idea is that when you're running a defrost setting, you probably have too much moisture inside the cab. Running the A/C compressor doesn't cool the truck when the heat is on, but it does act as a dehumidifier.
If your condensate drain is stopped up, it would cause a leak into the passenger floor. Look from underneath the truck on the passenger side around the firewall, under where the heater/evaporator box is, and you'll find the condensate drain. Clean it carefully, compressed air is best. I once tried sucking on one with my mouth and ended up with spider eggs in my mouth. Not a good idea.
You should also lift the hood and check the cowl area. That's where fresh air is brought into the hvac system. A lot of times leaves or other little debris will get in there and cause water to get into the cab.
If it's not on the passenger side though, and maybe even if it is on that side, most likely you have a leaking windshield seal. That's not uncommon at all, actually. Once you've exhausted your other "fixes," hunt down a windshield shop. Having your existing windshield resealed should run you less than $100.
