My fan speed stops increasing at speed 5 but it only happens when the vent setting is on the vents facing the driver and passenger. Any ideas or suggestions?

Hello,

It sounds like the control head could be out. To be sure lets check the fuses that run the system first. Here is a guide to help us with the fuse locations and the blower motor wiring diagrams so you can see how the system works and which fuses to check:

If all fuses are okay a CAN scan will help find a trouble codes for us.

If the control module is bad here are the repair instructions below. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
