A: Disconnecting the negative battery terminal for 90 seconds stops Air Bag deployment before you can work on removing the windshield. First remove the windshield wiper arm cover then proceed to take off both left and right front wiper arms with their connected blades. You should first remove the cowl top ventilator louver covering on both sides and the cowl top seal. Also extract the hood to top seal and both front door scuff plates before proceeding. Unfasten cowl side trim boards and front door opening trim Weather Strips on both sides before taking off the assist grip, visor assemblies, visor holder, personal light assembly, room light assembly, and front pillar garnishes from their positions. Lower the front headliner section progressively without destroying it after that remove interior rear-view mirror components and the windshield outside trim by cutting it carefully. Separate the No. 1 and No. 2 stops on the windshield glass as you grasp it through suction cups to avoid dropping it. Protect the glass-installation area with tape before threading a piano wire through body and glass from inside until you reach each end and secure them with wood blocks. Use piano wire to pull the adhesive from the windshield glass while avoiding the painted areas and decorations. Place a plastic sheet over the wire and safety pad to shield their surface from scratches. When the glass stays for reuse record its location on car surface before gently taking it off with suction tools to maintain as much adhesive left on the vehicle body. Use a scraper to carefully take off all window glass adhesive from its position and install a new one in its place. After taking out existing No. 2 and No. 1 windshield glass stoppers of 2-piece types you should install fresh ones.
A: Prior to taking out the windshield disconnect the battery cable from the negative terminal and give it 90 seconds to stop Air Bag and pretensioners from activating. Start by taking out the front door scuff plates, door opening trim Weather Strips, and front pillar garnishes along with inner rear view mirror. Next remove the cowl side trim sub-assemblies, assist grip cover, visor assemblies, map light assembly, and windshield moldings outside. Also detach the front wiper arm head cap, wiper arms, hood to cowl top seal, cowl top ventilator louvers, Weather Strips from both front doors, scuff plates and assist grip cover. Lift the roof headlining segment and take out the front wiper arm head cap along with both wiper arms and the hood to cowl top seal plus ventilator louvers on the left and right. Only cut through old windshield moulding from outside to avoid vehicle body harm then remove the glass through these steps: tape the outer surface, put wire under glass and body, mark points if needed, insert wire and remove glass with suction cups. Remove any damaged stoppers and dams from the windshield glass while also cleaning the outer edges with white gasoline. To protect the vehicle body during cleaning use a tool to cut away excess glue then apply a safe cleaning product.
Q: How to remove and install a windshield on Scion xA?
A: You should disconnect the negative battery cable followed by waiting for at least ninety seconds to keep the Air Bags along with seat belt pretensioners from activating. First detach the front door opening trim Weather Strip LH and RH along with front pillar garnish LH and RH, visor assembly LH and RH, assist grip sub-assembly, visor holder LH and RH, map light assembly, and roof headlining assembly by slightly lowering their installation areas rather than complete removal. Warming the installations surfaces for seals with a heat light will allow you to remove the inner rear view mirror assembly along with the front wiper arm head cap and front wiper arms LH and RH together with the cowl top ventilator louver LH and RH and hood to cowl top seal and front fender to cowl side seals LH and RH. Carefully cut the windshield molding from the outside with a knife while protecting the vehicle body before removing the glass through piano wire installation followed by exterior surface tape placement and matchmarking if using the glass again and adhesive cutting and stoppers disengaging before using suction cups. Start by cleaning the instrument panel and installing a new No. 1 instrument panel cushion before cleaning the windshield glass together with the vehicle body while leaving maximum adhesive on the vehicle body. The installation process starts with new windshield glass stoppers of type No. 2 and No. 1 followed by application of Primer G to installation components and placement of the windshield glass adhesive dam. The installation process calls for windscreen glass to receive Primer G application before receiving a new windshield moulding. Use suction cups to position the glass correctly with matchmarks aligned before applying Primer M to the visible part of the body and applying Part No. 08850-00801 adhesive or its equivalent to the glass for installation to the body ensuring proper fitting and cleaning away excess adhesive. Finally, reinstall the front fender to cowl side seals LH and RH, cowl top ventilator louvers LH and RH, hood to cowl top seal, front wiper arms LH and RH, front wiper arm head cap, roof headlining assembly, visor holders LH and RH, visor assemblies LH and RH, front pillar garnishes LH and RH, map light assembly, assist grip sub-assembly, front door opening trim Weather Strips LH and RH, and inner rear view mirror assembly, check for leaks and repair as necessary, reconnect the cable to the negative battery terminal, and perform initialization for certain systems.
