If your rear window is broken, the cost to replace it will depend on the make, model and year of your vehicle. For example, a rear window for a Honda Civic from the years 2001-2005 will cost around $200-$250 to replace. However, if you have a more luxurious vehicle, such as a BMW 7 series, the cost to replace the rear window can be upwards of $1000. In addition, the type of glass that is used for your rear window will also affect the price. OEM (Original Equipment Manufacturer) glass is typically more expensive than aftermarket glass. So, if you are looking to get your rear window replaced on a budget, aftermarket glass may be the way to go.
