Having problems with your 1999 Chevrolet Silverado 2500 ?
No heat 1999 Chevrolet Silverado 2500 no heat. I installed a new thermostat+coolant? + my dashcluster miles light has stopped working.
If it had dexcool orange coolant in it, the heater core is probably plugged, pull off the hoses and blow air through it, the dexcool breaks down and clogs everything. I had this problem a month ago and the core was plugged badly. Hope this helps
