There are 5 speeds on the AC/heater fan. First, speeds 1 and 2 stopped working And Now, speeds 3 and 4 stopped blowing. Only speed 5 works. Is the problem fuses, a switch, or the blower motor? thanks, jim

You will find a blower resistor near the blower motor , it goes into tho the housing with a harness of 5 or 6 wires, replace it

    nest step is to check voltages from the switch to the resistor

My ac/heater fan stops blowing then it blows sometimes? The air is still cold just not blowing out. when it does blow it is cold.

replace fan speed resistor block if this only happens on lower fan settings if it happens on high fan speed also, replace blower fan

My ac/heater fan stopped blowing. There were no previous problems with the ac. How can I tell if it's just a blower fuse or the fan/motor itself. And where is the blower motor located?

Does it work on all speeds, or has it only stopped on #1 speed for instance....the blower motor is located at the passenger side footwell...

2001 Jeep Wrangler heater blower stopped working

Yes I would go with the switch, BUT, does it have a resistor bank? That is, how does it reduce the speed? Many systems use resistors to lower the speed. Burnt or bad connections can cause this as well.
You can test the blower motor by connecting direct power from a source like the cigarette lighter if you are handy.
Most of the time the lower speeds konk out but the high speed continues to work this is the resistor bank that goes out.
