The problem of Fiat rear lights.

Model: Fiat Qubo MK 1 - Years 2008-2019
Part: Tail light

In this video, we see how easily a common electrical problem can occur on many Fiat vehicles - in this case, we see a Qubo - where a loose ground connection causes the rear brake light to flicker when braking. We must identify the loose, oxidized, or damaged ground wire through a visual inspection, and also perform a test with a multimeter to measure the resistance between the ground point and the negative pole of the battery: high resistance indicates a contact problem. We must then clean the oxidized or dirty contact points with fine sandpaper or a metal brush, and apply an anti-corrosion product. If the ground wires are damaged or worn, we must replace them or add additional ones; we will also check all connections using quality connectors; we will also check the ground points of the rear light cluster, where problems often occur. In newer vehicles, the CANBUS system can be sensitive to electrical resistance variations, so it is important to use compatible components.

How to Check the Oil Level on a Jeep Renegade?

This should be pulled out and thoroughly cleaned with a cloth: once cleaned, reinsert it back into its tube and pull it out immediately after. This way, you can check that the oil mark is between the minimum and maximum levels; finally, you can place the dipstick back in its tube.
