Pre-MOT Inspection Checklist for Chevrolet Gmc Blazer V6 Owners
These checks follow this Chevrolet Gmc Blazer V6's own most-recorded failure strings, starting with what a tester is most likely to flag on a Chevrolet Gmc Blazer V6.
-
the suspension joints — “ball joint dust cover severely deteriorated”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
-
the lights — “position lamp not working”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
the windscreen — “windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
Derived from the DVSA failure strings testers recorded for the Chevrolet Gmc Blazer V6. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
