Blown Heater Hose
Several months ago my heater hose blew (the end that attaches to the firewall) in my 1992 190e 2.3. I cut and capped off that hose and the the other one until I could get a replacement. It was the middle of the summer and with no need for a heater, I didn't replace it until just recently. I also replaced the thermostat and a couple of other hoses. Now, I have heat coming from the outside vents, the windshield, but not from the center vent. Does anyone know what's causing this?
