Smoke coming out of vents
Friday I was going down I-95 running the AC on the low setting and when I pulled up an exit ramp I started smelling something like leaves burning. And then all of sudden I had smoke (not mist) coming inside the cab. I cut the AC off and the fan off and it quit smoking. I think the problem is the fan blower. It does work on the high fan (setting and nothing on the lower settings) Has anyone ever had this happen, if so, I hard is it to replace and how costly. Any help would be appreciated. Oh by the way it was hot as hell Friday too.
