I took out my ICU to repair the capacitor for the defrost but I noticed there was awful amount of burnt spots in the icu so I went ahead and replaced capacitor anyway. Now my turn signals dont work at all but my hazards are working . So Im assuming my Icu is dead now maybe I made it worse. let me know your thoughts thanks
The ICU only controls the front side markers front and rear signal lights and signal light indicators are controlled directly off the signal light switch.
Check the signal light fuse.
