Maintenance/Repairs

When the car is running these thing work only intermittenly and are working less over time: Windows, door locks, climate control (almost never now!), courtesy lights and blinkers.BUT, when key is in on position and engine is not running, all work!

Any clues? We have changed the ingnition block & now may try replacing the LCM.

when not running the engine, you are working off the battery. when the engine is running, you are working off the alternator, I suggest you have the alternator/voltage regulator and its drive belt checked.

Find and clean the engine to body ground wire. Can’t find it? Make one.

Thanks! Yes, last we had it checked they said it was fine. But, that makes the most sense. Will try again, thanks!
