no heat in the cab
what is the proceedure to replace heater valve and what i kind of time frame on 1996 Chevrolet 1500 Pickup
Agree with Roy most likely a bad thermostat. here is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
could be thermostat, low coolant level, mode door failure or a clogged heater core. any one of these could be your issue. get a shop to check it for you.
i replaced the thermostat this morning, still no heat. pulled out the heater core and checked the mode air mixing door from cool to heat and it was working fine. replaced the heater core and that seemed to be the problem. thanks everyone for the help
