12-Volt Heaters?

I have no experience with a heater core in this truck, so I am not second guessing you. But I had a mechanic tell me that I would not have to remove the entire dash on my truck - just the glove box.

According to him, it was 1997 (newer body style) when it became more difficult on the F-150's.

Again, I have no experience, so I have no idea.

I have a 93 F150, and about 2 winters ago I couldn't get hardly any heat at all in the cab. I thought it was going to be a major deal, but a friend who is a mechanic and I started checking, and when we pulled the thermostat it fell apart in our hands. Once we replaced it I had plenty of heat. You've probably already checked the thermostat, but if not, it might be worth a look. I always try to check the easiest possibilities first. Good luck.
