(W) LH REAR QUARTERLIGHT (JCB JC332/R0638)

A damaged rear quarterlight can compromise visibility and security in a vehicle. During inspection, a cracked or broken quarterlight may allow moisture or debris to enter the cab area. The JCB catalog reference for this part is JC332/R0638, and it is an aftermarket replacement component. This part type serves as a fixed or hinged window panel located at the rear side of the cab structure. A common failure consequence is that a shattered quarterlight can create sharp edges or reduce driver awareness of surrounding conditions. Keeping a quarterlight in sound condition helps maintain a sealed cabin environment. Verify the serial number or application, then call (562) 693-7748.
