Heating

[Rikmister1]

Morning guys. I have no hot air blowing for the interior heaters. Think the motor has packed up. Does anyone have a wiring diagram or any experience/advice. I believe this is the motor in question

It's easy to test those. Just plug them back in and mess with the selection dials. They control the flaps the redirect air. If your fan has blown, then you won't hear any difference when you change the speed.

Also try feeling if the heater pipes in the engine bay are warm. I have read the at the coolant line can get blocked.

The flaps redirect and the pipes are hot. It just won’t blow hot air. I assumed this was the temp flap motor but not sure

Those motors are easy to test. I think there is a thread on rx7club about it. Think they also show how to fix one if it's bust.

This is the link, though it's for the touring climate control so not sure it will help

Anyone know how to rebuild actuators? - RX7Club.com - Mazda RX7 Forum

3rd Generation Specific (1993-2002) - Anyone know how to rebuild actuators? - My '94 touring model has a failed temperature actuator (FD01-61-A60). This isn't available basically anywhere, so I'm hoping someone knows how to repair/rebuild it (or some other random thing that can take it's place)...
