Antenna Leads and Defroster Grids on the CD3 Backlite
Verifying the grid layout on the replacement back glass is the first thing I do before bringing it to a Ford Fusion. The early 2006 to 2007 production runs, corresponding to original part numbers like 6E5Z-5442006-A and 6E5Z-5442006-B, feature an integrated AM/FM radio antenna grid embedded directly into the upper section of the glass above the defroster lines. This layout requires an active on-glass antenna amplifier and a dedicated coaxial connector lead right at the glass edge. When Ford updated the vehicle for the 2010 to 2012 model years across the S, SE, SEL, Sport, and Hybrid trims, radio and satellite reception shifted to a roof-mounted mast, changing the internal wiring and superseding the glass to numbers such as AE5Z-5442006-A and BE5Z-5442006-A. Matching the grid pattern prevents losing radio reception entirely.
I also inspect the heated window defroster busbars and spade terminals on the bench. Because these stationary tempered panels rely on climate control relays to melt rear ice, damaged or cold-soldered electrical contacts cause instant circuit failures. A common issue on these cars stems from broken lines or snapped spade terminals caused by previous aggressive window tint removal or careless cleaning on the parcel shelf. When supplying replacement rear glass for this platform, I install aftermarket panels manufactured by brands like PGW, FYG, Pilkington, or XYG, all of which reproduce the factory solar-green tint without the dark privacy tint found on crossovers or wagons.
Encapsulated Mouldings, C-Pillars, and Lower Stop Blocks
The perimeter profile demands close physical inspection before the glass touches the car. The upper and lateral edges carry an encapsulated reveal moulding, while the bottom sits against specific locator stop blocks set along the lower body flange. Ford issued Technical Service Bulletin TSB 10-16-6 specifically targeting loose or peeling lower mouldings at the base of the rear window on 2010 models, so I make sure the bonded lower seal on the new glass is firmly attached and seated straight. If this lower moulding lifts, wind noise and standing water build up along the trunk transition seam.
Cabin clearances are equally tight around the interior edge. The rear glass directly borders the upholstery of the rear package tray, the interior C-pillar trim panels, and the trailing lip of the headliner. On these cars, the headliner fabric is notorious for separating and sagging at the rear glass boundary due to sun exposure and failing adhesive, meaning rough handling can pull the headliner board down completely. Down along the center of the interior parcel shelf sits the high-mount third brake light. I make sure the glass ceramic frit band lines up cleanly around the brake light housing so there is no interior light bleed reflected into the cabin during braking.
Checking Surface Glass Clarity and Parcel Shelf Alignment
Once the back glass is in position, I check the clarity of the outer tempered surface. Ford issued Special Service Message SSM 48130 regarding chemical etching and orange-peel surface hazing on side and rear glass caused by harsh hydrofluoric acid detergents in commercial car washes, so I verify the aftermarket replacement has a clean, uniform float finish with zero distortion. Because the CD3 platform shares its body stamping with the Mercury Milan and the Lincoln Zephyr and MKZ, the outer frame matches precisely, but internal gaps around the rear parcel shelf must be even from side to side.
A final electrical continuity test confirms the spade terminals did not lift during connection. The horizontal grid lines must heat evenly across the full width of the heated backlite, and the interior C-pillar trim covers must snap back into place without pinching the defroster power leads or the early-model coaxial antenna wiring against the steel frame.
