Fitment and application details

FCS 84645 is a back glass lift support for 1993-1998 Mercury Villager and 1993-1998 Nissan Quest models. Use the listed dimensions to confirm the replacement matches the original support length and travel before installation. The FCS line is positioned as a focused replacement product line for body and glass-related components, making this part a practical choice when servicing rear hatch glass support hardware.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common replacement reasons

• Rear glass drops too quickly when opened
• Lift support no longer holds the back glass in position
• Uneven or weak opening action at the rear glass
• Original support has lost pressure over time
• Back glass requires replacement after wear or age-related failure

Installation notes and tips

Verify compressed length, extended length, and stroke length against the original support before installation. Confirm the vehicle application as 1993-1998 Mercury Villager or 1993-1998 Nissan Quest, and compare the mounting points and orientation to the removed part. For best results, replace worn lift supports when the rear glass no longer opens or stays supported consistently.

Quality assurance
