Hello, I am Randall. I have reviewed your question and working on it now. Will return shortly
Most commonly we see the blower motors sticking. If you can get to the blower behind glovebox/up under dash on right side,, turn key on and set blower on HIGH. begin tapping fairly hard with small hammer or similar on and around the blower motor itself. In most cases it will come back on. If so? this indicates you do have a blower failing. I really am not leaning to control panel but,, the blower module/resistor is a possible to hitting hard on blower with blower turned on helps to diagnose this
how do you get to it...do you have to remove parts?
the blower basically point straight down to floor up under passenger side dash. I cant remember if you can just remove the panel under dash and view it or if in fact you do have to remove the glovebox. hard not being there. Here are directions for changing it which kind of lead you to it. Click HERE
I am failry certain you can vie the blower from up under passenger dash
how do you tell if it's a fuse or a resistor?
You unplug blower and use testlight to see if power there OR check the blower fuse. You then get to blower and backprobe the ground wire at blower connector and jump to ground. If no blower? then bad blower. if blower runs, suspect bad resisitor. I have normally only seen blowers fail when you lose 100% blower as the resistor is what controls the speeds
