Jeep Grand Cherokee WJ Left Mirror

A complete left mirror assembly for a Wrangler JL (2018+) with power adjustment and turn signal costs R3,500-R6,500, while a basic manual mirror for a TJ (1997-2006) runs R1,200-R2,800. If only the glass is cracked, replacement mirror glass alone costs R450-R1,200 depending on whether it's heated or includes a blind-spot indicator.

Yes, if the housing and adjustment mechanism are undamaged, replacement glass for a Grand Cherokee WK2 costs R600-R1,500 and clips or adheres into the existing backing plate. This works well for stone chips or cracks but won't fix broken motors, turn signals, or housing damage from parking lot impacts.

The assembly includes the base housing (bolted to the door), mirror glass with backing plate, adjustment motor (on power mirrors), cover cap (often painted body color), and on models like the Wrangler JL and Cherokee KL, an integrated LED turn signal. Heated mirrors add a defrost element behind the glass, while blind-spot warning mirrors include a small convex section.

Vibration typically means loose mounting bolts at the door hinge, a cracked housing from previous impact, or worn bushings in the base—common on high-mileage Cherokee KL and XJ models driven on rough Johannesburg roads. Tighten the three door-mounted bolts to 8-10 Nm and check for cracks in the plastic housing that allow flex.

Small cracks in the housing can be epoxy-glued and reinforced from behind if the mounting points are solid, saving R2,000-R4,000 on a new assembly for models like the Gladiator or Compass. However, if the mirror won't adjust, the turn signal is damaged, or the housing is shattered, replacement is safer—used assemblies from Jeep wreckers cost R1,500-R3,000.
