Question type: Maintenance & Repair

I don't appear to be getting enough heat aimed at floor boards. Is the most likely

These vehicles have issues with the blend doors breaking inside the heater box. It's not an easy fix! The entire dash assembly has to come out! Unless you have to go in there to replace a leaking heater core, it's not worth fixing! Hope that helps! Jim
