I have a 2003 Ford ranger. The last two weeks every time I drive my windshield and windows will fog up to the point where I have to continuously wipe my windshield while driving. I am not having any overheating issues, the truck runs fine. There are no obvious signs of coolant or anything leaking, I continuously check to be safe. It typically only happens for the first 15 to 30 minutes of the truck being on. I do usually let the truck warm up for 10 to 15 minutes before I drive it.
When it first started happening it wasn’t regularly causing the windshield to fog up. It would happen maybe once or twice a week. Took it to the shop and they couldn’t figure out what was wrong.
But as it now happens almost every time I drive the truck it is driving me nuts to have to continuously wipe the windshield to see while driving.
Does anybody know what the issue could possibly be?
