Q: How to remove and install the windshield glass on 2007 Toyota Prius?
A: The first step when removing the windshield glass involves disconnecting the negative cable from the battery terminal followed by a 90-second waiting period to stop Air Bags and the seat belt pretensioners from activating. The windshield glass replacement starts with removing front door scuff plates (LH and RH) and cowl side trim boards (LH and RH) together with front door opening trims (LH and RH), front pillar garnish corner pieces (LH and RH), front pillar garnishes (LH and RH), visor assemblies (LH and RH), visor holder, assist grip cover, assist grip sub-assembly, map light assembly. Workers should lower the roof headlining assembly without complete detachment. Continue with the procedure by cutting off the windshield moulding outside along with the inner rear view mirror assembly (with or without EC mirror), hood to cowl top seal, front wiper arm head cap, front wiper arms (LH and RH), cowl top ventilator louvers (LH and RH). Install piano wire between the glass and body before cutting through adhesive by tying handles to the wire ends. During this process maintain caution to avoid touching or damaging the exterior paint of vehicle and its ornaments. Suction cups enable the glass removal process after the stoppers are disengaged. Remove all damage in the windshield glass by first removing stoppers and dams before doing a white gasoline treatment to the outer edges. The body contact surface needs cleaning which requires removal of excessive adhesive followed by use of a cleaner. Primer G application follows on the glass where the No. 2 windshield glass stopper will go along with drying time before installing two new stoppers. Reinstall the No. 1 windshield glass stopper on the vehicle body after completing the same procedure. Install the window glass adhesive dam by positioning it on the glass with area A excluded then use suction cups to place the windshield glass while ensuring an even contact surface and proper aligning of the matchmark points. The vehicle body requires Primer M treatment and the glass needs Primer G before Toyota Genuine Windshield Glass Adhesive or equivalent gets applied to the glass surface. Secure the glass to the vehicle body while keeping it aligned with matchmarks before placing protective tape until the adhesive solidifies. Finally, install the windshield moulding outside, cowl top ventilator louvers (LH and RH), front wiper arms (LH and RH), front wiper arm head cap, hood to cowl top seal, inner rear view mirror assembly (with or without EC mirror), roof headlining assembly, map light assembly, assist grip sub-assembly, assist grip cover, visor holder, visor assemblies (LH and RH), front pillar garnishes (LH and RH), front pillar garnish corner pieces (LH and RH), front door opening trims (LH and RH), cowl side trim boards (LH and RH), front door scuff plates (LH and RH), check for leaks and repair any with auto glass sealer, reconnect the cable to the negative battery terminal, and perform initialization for certain systems.
