Sunroof: Diagnosis Mercury Sable V

Inspection and Verification

1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical or electrical damage. VISUAL INSPECTION CHART Mechanical Electrical Roof opening panel Roof opening panel frame Roof opening panel drain hoses Roof opening panel lifter assemblies Roof opening panel water trough Roof opening panel air deflector assembly Roof opening panel seal Roof opening panel shield Smart junction box (SJB) fuse(s): 19 (25A) 41 (15A) Circuitry Accessory delay relay Roof opening panel motor and module assembly Roof opening panel switch
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the concern is not visually evident, determine the symptom. Go to «Symptom Chart - Roof Opening Panel»(ref-293467-S21157341842008080700000) or Go to «Symptom Chart - Noise, Vibration and Harshness (NVH)»(ref-293467-S21071178042008080700000) .

Symptom Chart - Noise, Vibration and Harshness (NVH)

Note. Noise, vibration and harshness (NVH) symptoms should be identified using the diagnostic tools that are available. For a list of these tools, an explanation of their uses and a glossary of common terms, refer to NOISE, VIBRATION AND HARSHNESS article. Since it is possible any one of multiple systems may be the cause of a symptom, it may be necessary to use a process of elimination type of diagnostic approach to pinpoint the responsible system. If this is not the causal system for the symptom, refer back to NOISE, VIBRATION AND HARSHNESS article for the next likely system and continue diagnosis.
