Well the ol 86 na started farting on me again this morning.. Long time since its done this to me. Heater doesnt work.. bleed the system. Checked the fuses. All of that is good to go. When I change the temp on the heater control it doesnt switch from hot to cold. Yes I've had that part of the dash out here lately. But the connection is still good and tight, electrical that is. Checked for flow in the heater core. Its fine. No leaks and water flowing like a river. Is there a seperate fuse to control the motor that switches it from hot to cold air? If so is it located in the same panel as the heater fuse (passenger side kick panel)? Its not cold here.. but I just dont like when things start going wrong. It drives me nuts.

is your hot/cold sensor behind the passenger dash working/ connected? i know mine was doing the same thing until i connected it.
