The front blowers in our 01 Chrysler Town and Country started only working on high for the longest time and then completely went out. The blowers in the back work fine. We replaced the resistor behind the glove box, but that didn't help. We've checked fuses as well and they are all good. Not sure what else to do and we cannot afford to get it looked at.

Hi, since you know where the resistor is, that is a good place to troubleshoot the system. The problem is probably the switch but may also be the motor. You will need a 12 volts test light to troubleshoot. You can get a test light for less than $10 if you don't have one.
First, pull the connector off the resistor and connect your test light clip to a good ground point (bare metal spot on the frame of the dash.
Verify the relay and fuse are good by turning the key and switch on and probing the dark blue wire at the resistor connector terminal. If there is no power there, the problem is the fuse or relay in the box under the hood.
If power is there, next check the switch by moving your test light clip to the terminal of the dark blue wire (key and switch still on, so you have battery voltage on the wire).
With the switch set to "1", probe the dark blue wire with the brown stripe. If there is no light the switch is probably bad. Check a few of the settings. For example, with the switch on "2", you should get a light by probing the dark blue wire with the orange stripe. On setting "5", you should get a light on the dark blue wire with a green stripe.
If the switch is working, the blower motor is probably bad.
If the switch is not working, check the ground connection to the switch.

1. Pull the cup holder out, then remove the small plastic trim piece between the cup holder and the HVAC control panel/radio bezel.
2. Loosen the 2 lower and 2 upper mounting screws, then remove the HVAC control panel/radio bezel.
3. Disengage the wiring connectors from behind the HVAC control panel switches.
4. 
   
5. with your test light clip still connected to the hot wire of the resistor connector, probe the terminal at the black wire with an orange stripe. If there is no light there, trace the wire and repair the connection to chassis ground.

Check if the blower is getting power 12 VOLTS,and GROUND if it is, then the blower is bad. turn it on and rap on it with a hammer, if it starts to work its BAD.
