Heater does not warm up. Ran the truck for an hour and no heat to defrost windshield. This also occurs while driving and the defroster won't clear the windshield, and have to resort to using a rag. Looked for possible causes on the internet, and found this is a common complaint. There are many articles suggesting where to look for resolution. There was a similar complaint on this site listed under other from January of 2025. Being unable to keep the windshield clear with the defroster is a safety risk due to poor visibility or distraction while using a rag to clear it.
