Cicco,
I thought I needed a new heater control panel, but a parts salvage guy suggested that the my problem (first and second fan speeds didn't work) was likely the resistor pack on the blower assembly. I replaced that part and all was good.
But just to let you know what I found:
- Comparing the parts diagrams for the EX and LX and it looked like I would need the EX climate control panel, the sun sensor that goes in the center of top of the dashboard, and the motor speed control module (sorry, forget what it was called, but it is used in lieu of the resistor pack to provide continuously variable speeds instead of just 4 discrete speeds).
- I did not get to the point of finding out whether the blower/motor assembly and the wiring harness were the same before I found out about my easier fix.
If your heater control panel is actually gone, it may still be worth looking into this further as the EX control panel is much easier to get (and cheaper!) than the LX panel.
