After 5 years of good use of about 20x per season, my left glove gives no heat. My right works well. I switched the plugs from the harness and it is the glove not the harness. Emailed Gerbings a little while ago and no response. These gloves were bought used, so no warranty. Does anyone know if Gerbings would repair the glove for a fee or replace it for a fee or do I just need to bite the bullet and buy new gloves?
