My '92 has no bad wiring except for the now bypassed drivers window circuit breaker. The rest is completely stock...radio and all.
My '97 had a shorted lumbar support which affected everything else in the same module circuit...interior lights & door locks operating by themselves.
Problem went away when I disconnected the lumbar support wiring connector after setting it in a good position. The rest is completely stock...radio and all.
Of course both are in Tennessee where there's hardly any snow and road salt.
