LOGICON (NEW), 86-92
New Mazda OEM “Logicon” (Heater A/C Control) Unit for all 86-92 RX7’s.
These units DO die. Another frustrating problem is the Air Mix Motor (listed below). Sometimes the air mix motor died and killed the Logicon. Sometimes the Logicon died and took the air mix motor with it. Every once in a while only the air mix motor is dead and the Logicon is fine.
All of the above is why there is NO returns, no exchanges, and essentially no warranty on these NEW Logicons.
