A family member of mine just got a 1995 chrystler LRS from an in law..The car has sat since spring of 2005... Well the in law told him that the only thing that needed to be changed was the belt.. So he changed the belt and the car does run good for the few mins that they had it running but now theres no air coming out to heat the inside of the car... He thinks it could be a fuse that needs to be changed or it could be the fan to the heater.. My question is, could it be the fuse or the fan for the heat to not be working?? or could it just take time to work since it sat for so long?? Any advice would be so appericated....

Put the key in the run position but don't start the car.
Turn the heater to max and move the fan switch to different positions.
No fan noise or air blowing out - fuse or fan motor dead
--check fuse 21.. a 25amp fuse
Fan noise only at full or other settings - fan switch reostat is bad
Fan works as it should but makes sound like a baseball card on a bicycle spoke - garbage or leaves in fan motor housing.

The fuse is for the fan (which is an electrical motor). If the fan doesn't blow air past the heater core (which is a mini radiator inside the car) you won't get any air blowing into the car. You should be able to make and hear the fan work without turning on the engine. Turn the ignition key until all the dash lights light up....you have all the electrical powered. Now find the fan switch and crank it on high. You should hear a whooshing noise of air movement. The fan works. Car running or not. If you don't hear fan running look in fuse box for appropriate fuse and check it. It is either good or it ain't. When in doubt - switch with another of the same amperage that you know works.
Heat comes from running the motor for the motor makes the heat which goes into the coolant(which is circulated partially thru the heater core and radiator to be cooled off by the fans. Fan should work right away, heat takes longer. If you can hear the fan going but can't feel the air, it is the directional controls you have to figure out and he should still have the owners manual.

If it is the fan just not coming on, yes it could be a fuse, relay, or the fan blower motor.
However if you can hear the fan but feel no heat just air it could be something else in the cooling system; such as a closed thermostat, leaking hose, clogged radiator/heater core, or an low amount of coolant.

See answer # 1 (wolfyss)......dead on.
No fan/air blowing = fuse.
fan and no heat = low coolant (the heat is obtained from the engine coolant, when you select heat, a valve opens allowing hot engine water/coolant to enter a smaller radiator inside the passenger compartment - called the heater core...this does exactly the same thing as the main radiator...it radiates or gives off heat....that is the purpose of the way a radiator is constructed....all those little vanes of metal provide a huge amount of surface area to disperse more heat than just a pipe would)

No, it won't make your heater supply up working. there are countless areas to the A/C device nonetheless, and while you're desirous to take all of it out that's rather a activity. there is the pump pushed via belts fixed onto the engine, there are areas up front that appear like a radiator, there are areas decrease than the sprint too. and of course there are hoses going between those type of. while you try to save weight, perhaps for racing? then you definately would desire to in all probability save 40-50 lbs in keeping with what form of motor vehicle that's.

no time wont help.......either the fuse,heater switch,or blower motor.............try the fuse first.

it could also be the thermostat and that is an expensive fix.
