Heater
My heater won't work, I don't any signs of a leak, my floor is dry. A clog maybe? Something not working? Give me some ideas
|
give us an idea ... what year truck you have ? what engine does it have ? how many miles on it ? what about the heat don’t work ? fan blow ? blend door move ? |
Heater
It's a 99 4.2, blower works, I can hear blend door move. AC kick like a MF but just no heat
|
get the motor up to operating temp.. pop the hood and feel the 2 small heater hoses going into the firewall... are they both warm or hot... |
the two hoses should be hot
|
Heater
They're pretty warm but I wouldn't say hot
|
what is the coolant level?
|
Heater
Full, brand new fluid last month
|
is your heater control working properly.. it switches from hot to cold.. no sure if 99 has a blend door. if both hoses are getting warm .. that tell’s you , you have flow through the heater core.. you have no heat whatsoever in the cab ? |
Well when I turn the nob it goes from cool to cold so I would assume it's working, haven't had the weather to get in there
