Why Repair Your Heated Rear Window?
A functioning rear defroster is crucial for safety and visibility. Damaged heating elements—often caused by scrapers, tint removal, or wear—lead to uneven defrosting. While replacement windows cost £150-£400, a quality repair kit (£15-£50) can restore functionality for years. According to auto electrician James Dalton, “90% of grid failures are repairable if using proper conductive compounds.”
