Several electric issues

[Almomen]

E500 parked for more than 1 year, when tried to drive it this winter I noticed that several electrical issues happens in the same time, the left headlight wiper motor ( not fluid spray), the left high beam light, the driver side visor light, high and low beam flicker , all not working . It seems that all related.
Is it grounding issue , is it relay I need help

@Almomen, First thing I would do is check all of the fuses in the fuse box. Take them out and be sure there is no corrosion in the connections or cracked fuses. Secondly, make sure all the fuses are brass. Change out any aluminum fuses.

This is the place to start and it may or may not fix the problem but eliminates a lot of electrical gremlins.

Headlight/wiper issues could be the headlight switch, high beam / turn signal combo switch, or wiper combo relay. As Terry noted above, check all fuses first (remove / clean contacts, re-install).

The visor light is likely a separate issue, not related. Clean the electrical contacts at the visor clip.

Otherwise, you'll need to study the schematics in the ETM and see if you can figure out the possible causes:
