Intermittent suspension light

[high mileage]

2010 Denali 6.2. has the z55 suspension with an intermittent light for the right rear shock. I plan to check wiring and apply deoxit to the connector, but can these be repaired or do they have to be replaced?

What is the code that you are receiving?

No, they cannot be repaired, at least by you.

I had that connector come loose somehow but as @Joseph Garcia said it may be time for new ones.

Perhaps you mean C0590? If so, here's the description and diagnostic path. Confirm that I selected the correct vehicle or navigate to the code page for yours.
