does anyone have a family member or someone they know who is a mechanic...i need some heat in my car...i have some when i am driving, but when you go slow or stop the air blows cold...we filled coolant, changed thermostat, heater coil is ok bus it blows really hot air after you have been driving it more than 45 mph for awhile...i am just so tired of freezing to death while i sit in traffic on Hwy 50 and then my windows are all iced up bcus no heat to defrost...
