SOURCE: 2001 dodge ram 1500, blower

the blower resistor is the most likely reason.. for that truck you may also find that its melted and will require the pigtail for the resistor as well

SOURCE: remove front axle from differential on 2003 dodge ram

That works fine on a relatively new vehicle but one that has run in salt etc you'll save a lot of time if you remove the steering knuckle completey by separating lower ball joint and outer tie rod end ball joint and bring the whole steering knuckle to a bench to separate the hub/bearing. Soak everything with penetrant, loosen the bolts a few turns and try hitting right on the bolt heads. I also made a very sharp wedge from a chisel and rammed it hard on the other side to seoarate the hub. It will finally come apart then you'll see all the **** that was binding it due to an alumininum knuckle re-acting with a steel hub. Clean the hole and grease everything and fit new bearings

SOURCE: fuel filter removal for dodge ram 1500 2003 model


The combination fuel filter and fuel pressure regulator is used on all engines. It is located on the top of the fuel pump module. A separate frame mounted fuel filter is not used with any engine.
Both fuel filters (at bottom of fuel pump module and within fuel pressure regulator) are designed for extended service. They do not require normal scheduled maintenance.

2003 dodge ram 1500......no heat


Does your heater motor run when you turn speed dial ? Have you checked the two hoses that run from the engine compartment to the heater core ? When car is at operating temperature, carefully touch both hoses which should be warm or hot. If only one if hot, then you may have a bad actuator. If both are hot, you may have a clogged heater core or none functioning heater motor. or resister.

If motor is not working, check fuses, if good, then check for power at the switch and then at the heater motor.

Heater wont switch to defrost


You have one or more broken blend doors in your HVAC plenum which was a common problem with 03's. You can buy upgraded parts from Dodge or better yet, go to www,heatertreater.net for an easier and more permanent fix.

Heater blows but no heat in my 2003 dodge ram 1500 4x4 with 4.7L engine. what can this be? its a 2003.


If your engine reaches normal operating temperature then it sounds like the heater valve is not operating. Find the valve on the engine firewall passenger side and manually open the valve. Find it by following the 3/4 inch heater hose to the firewall where it is connected to the valve. Most likely the cable ( or vaccum hose)from the temperature dial to the valve needs replacing.

No heat


You probably just need to backflush your heater core. You can use a hose to flush it back and then forward. You'll be surprised at how much sludge and gunk will come out.
