Having problems with your Dodge Ram 1500 ?

2003 Dodge Ram Van 1500 *** NO HEAT **

\015 I just discovered the other day when I turned my temp dial up to warm I am not getting warm air, the blower is working fine, the AC is OK, just no hot air. Anybody have any ideas where I should start to determine what the problem is??\015 Posted / edited by AnonymousUser on : 18-03-2019

Answers :

Do you have enough antifeeze in your cooling system. If not fill & check again for heat. You may have a blockage. If so remove the in & out hoses to the heater core on firewall. Be careful not to damage core. Use a garden hose to flush the core one side to the other untill running clear water. put one hose on tight & clamp, put other on loose. Have someone start engine & slowly remove loose hose to let air escape. when fluid appears put hose on & tighten. Refill rad & resevoir. Heat engine up & check for heat. Also heat cable may be off under dash.
Check the radiator fluid level, if that is good you will need to check the actuator on one of the two radiator lines that run back to the firewall. See if you can move this manually to open and close the valve lever. If you can then you either have a stuck cable in the temp control or faulty vacum switch or poor vacum leading to the control valve.
