1989 Plymouth Horizon Blower motor doesn't work

Heater problem
1989 Plymouth Horizon 4 cyl Front Wheel Drive Automatic

In my 1989 Plymouth Horizon, The blower motor for the fan and A/C doesn't work. I'm not sure if I burned out the motor or if I just blew a fuse. When I got the car, there was no owners manual and I looked everywhere for a diagram of the fuse panel to tell me what does what so I don't have to look at every fuse and wind up screwing everything up. I need to know which fuse I need to look at. And if it's not the fuse, I need to know where the blower motor is and how I change it. I already went through one winter without it and am not looking forward to another. Please, any help you can give me would be greatly appreciated. Thank you.
Do you

Hi: It took awhile but I found it. The fuses are as follow:
1) 20 amp (yellow) Hazard Flasher
2) 20 amp (yellow) Backup lights
3) 5 amp (tan) rear window defroster
4) 20 amp (yellow) 30 amp (lt green) with AC heater / AC blower motor
5) 5 amp (tan) Electronically tuned radio memory (1989)
6) 20 amp (yellow) stop lights, key buzzer
7) 20 amp (yellow) insterment cluster, park, side marker lights, tail lights, lic plate light, horn, horn relay, cig lighter, electronicly tuned radio light
8) Empty Not Used
9) Empty Not Used
10) 20 amp (yellow) electronic fuel pump
11) 5 amp (tan) gauges check eng light, eng temp warning, seat belt buzzer
12) 4 amp (pink) cluster lights
13) 20 amp (yellow) Windshield washer and wiper motor
14) 6 amp circuit breaker / rear wiper washer
15) 5 amp (tan) radio and clock power
16) 20 amp (yellow) turn signal lights
17) seat belt buzzer / key in warning
18) relay / horn
19) relay / hazard warning flasher
20) relay / turn signal flasher

OK I HOPE THAT HELPS WITH THE FUSES, MY EYES ARE GOING CROSSED. (LOL) Now, first check the fuse. If it's good, go to the switch and see if you have power. If there is power, try switching the speed control to see if there is power output. If so, move to the blower motor resistor. The blower motor is behind the glove box and the blower motor resistor is on the right side of the heater housing. Check if you have power to the resistor. If you do, then you need to turn to the motor which is behind the glove box. Check if it is getting power.

Now, if there is power to the switch but none out, replace the switch. If there is power to the resistor but none to the blower motor, replace the resistor. If there is power to the blower motor but it doesn't run, replace the motor.

Let me know if this helps or if you have any other questions. Seriously, do not go through the winter without the blower motor working! Let me know if you need more help.
