Climate Control Module Replacement, 1999 F350
Lately been having issues with my climate control not working. It's doing two things. One is that the fan sometimes just doesn't turn on at all. And other times I'll set it to AC for example, but it will continue blowing out the defrost instead of the vents.
Those issues made me think the control module itself must be shorting out. Here i go through replacing it. It's just plug and play. The only real challenging part is taking apart the dash to access it.
Now in the end, replacing this module didn't fix my issue. So next up will be replacing the blower fan itself.
