Any suggestions gladly accepted. I have water leaking somewhere behind the dash. Checked the door seals but that doesn't seem to be the issue. Are there any common areas on 99 F350's to look for. It's leaking onto the GEM, so I need to catch it quickly.

Windshield.
Very common.

Spray some glass cleaner (foamy type) around windshield and use a blow gun to blow air from inside out and if the windshield is leaking you'll be able to see it.


Also if you have perhaps a remote start or alarm somtimes when they run wires through the firewall into the rubber grommets, people don't seal them properely and I've seen those leak also.

Yup the windshield . Mine leaked, just about ruined the GEM. It would jump into 4WD at any time it choose to. had to put a cut off switch on the transfer motor so it wouldn't do that. Saved buying a GEM and programing . $420
