Changed my blower motor resistor today after I only had either 1 or full blast on the aircon and heater.
Took a few pics which someone might find useful.
The resistor is located under the glovebox in the passenger side footwell. There is a curved plastic cowl which sits under the box to stop your passengers feet kicking the plethora of connectors and cables under there.
Tools:
1/4 drive socket set with 7 or 8mm socket, 6" extension useful here.
# Phillips head screwdriver or socket.
1) Take off glovebox door with screwdriver - 3 screws underneath that attach the hinge to the glovebox casing.
2) Locate the 4 bolts holding on the curved plastic cowling. I've taken pics of these as I had a little bother finding them.
2 are visible inside the glovebox now that the door is removed. Also accessable from footwell but have to look in through glovebox to get to.
2 are underneath the cowling accesable from the footwell - u gotta reach up to get em. Only one pictured here, just feel for the other one it's to the rear in the middle.
3) Blower motor resistor is in a module with a plug coming out the back of it. Attached with 2 bolts. Pull off the connector (yet another different type of locking mechanism to hold this one in. How many different types are there?!).
4) Checkout rusted old unit. Swap in new unit, plug back in.
5) Test the blower before putting back together!
6) Stick back together and enjoy variable speed aircon/ heating.
