I need to replace the blower motor -need help on the HOW TO?
I need to replace the blower motor. I know where it is, right up against the firewall and is sealed within a plastic casing. I suppose I need to
1) cut the casing as stated on the casing ''cut here for service''
2) remove screws that hold the blower motor in place
3) I also believe that there is no way I can remove the blower based on the available space. I think I will have to remove what appears to be an a/c component sitting on top of the engine overflow tank. However I am not 100% sure. I also assume I don't need to disconnect any wires except those plugged into the old blower. When removing the a/c unit it appears I can just move it out of the way once bolts are removed (I see 3 bolts holding it down).
Anyone agree after trying the same set of tasks or had a different set of tasks or recommend an alternative plan? Anything else that I need to consider and take care of not noted above? Thanks

I think I'd try a new blower motor resistor first, as your going to need a new one anyway if it only ran in high speed. Look behind glove box, and under dash on passenger side and see where wires from blower motor are going back to. The connector where the blower motor wires attach to, is usually your blower resistor, held in with a couple of screws. If wires go through firewall, then look at back of engine area on firewall for it on passenger side. Everyone told me same thing, that the resistor will still supply power to motor, even if it's burned out, but mine quit after running on high for a while, and it was all I needed to replace to get everything working again. As I said, you'll need to replace it anyway right?
blower motor is in engine compartment against firewall behind windshield washer resivoir. resivoir and cruise control unit need to be removed to gain access to blower motor. be careful when unplugging connector as they are brittle.please rate if this helps.
The Blower Motor Resistor is located on the passenger side firewall, not far from your A/C's H-Valve (or expansion valve), going inside of the vehicle. The blower motor resistor has a 4 or 5 way black connector plugged into it and this is the only visible portion of the Resistor you will see. Remove the wiring connector and remove the 2 or 3 screws with an 8 mm or 5/16" socket (8 mm and 5/16" are the same). Once the screws or fasteners are removed, just pull the blower motor resistor out of the firewall and if you look at it, it will have various coils of wire on it, sometimes it will show burnt coils, but you can always check the various coils with an Ohm-meter.
Aside from that, install the new Blower Motor Resistor and Voilà! Your inside Blower Motor should work just fine.
A brief note here, if your fan doesn't work when the fan switch is on High, then it's not the Blower Motor Resistor, but possibly the Blower Motor itself. Should this occur, please get back to me insofar as how to replace the blower motor and why the blower motor's wires have to be twisted...even with the new blower motor fan.
My 2000 century heater blower died,dont replace the fan motor until you check with a simple test light to see if the heater fan resistor is bad first,it's only 20 bucks to replace.Its located next to the fan housing up against the firewall.The wires from the fan switch go down to the resistor, check to see if switch has power then check for power down at the resistor,I'll bet its the resistor.There are three, I think five sixteenth screws to remove the resistor one is crammed up very tight on the firewall,you'll need a quarter inch drive extension with a wobbly socket to get that one against the firewall.
The blower motor resistor is located on the back of the blower motor housing under the dash on the passenger side. It can be difficult to get at, but it is doable. Be ready with the ibuprofen the next day for your sore back.
Remove the cover panel from beneath the dash on the passenger side.
Unplug the power 'ribbon' wires leading to the resitor.
Unplug the wires that lead from the resitor to the blower motor housing. There are usually two, one black and one purple that share the same plug.
Remove the short hose that leads from the blower motor housing to the ventilation system ducts.
Remove the blower motor by removing the three hex screws that hold it in place.
Remove the resistor by removing the three hex screws that hold it in place. The resistor is right against the firewall so two of the screws are very difficult to reach. A slender flexible socket extension will make the job easier.
Attach the new resistor in place using the same hex screws. Only 1 or 2 of the original three are needed (the part is very light) if you do not feel like fighting with the ones next to the firewall.
Reatach the blower motor and reconnect the hose.
Plug the power cable wires back into the resitor and the wire from the resistor back into the blower motor.
