2 Questions

Got the truck last weekend and have 2 questions. 08' Kingcab 4x2

1. When the heater is on or defrost, sounds like there is a pressure release that is coming from under the glove box. It's loud enough to hear over the radio. Common?

2. Varying speeds, there have been times where the truck is shaking hard, almost like there is a flat or I'm going over very rough terrain (and I'm not) out of nowhere then goes away. Any ideas?

1. A/C compressor runs with the defrost, so what you are hearing is the evaporator in the HVAC duct. My 04 was loud also in the summer with the A/C on.

2. Take to dealer and have tires rebalanced, especially if you have stick on weights. They don't stay stuck to wheels too long.
