Blower fan not working on all speeds
Lately I have been using the AC alot and for some reason the fan doesn't work on #2 speed. It works fine on #1,3,&4 but nothing on #2. Could that be the blower motor resistor because usually that effects the high speed. Also is the blower resistor just a plain mechanic coil or electronic in the H3? What else could it be?

its a series of resistors, all are in the circuit for slow and they get switched out as u go up in speed. in high speed a relay closes the circuit completly.
you have an open resistor,or a bad contact due to heat distortion of the connector.

there's a bunch of pix here somewhere,,,search
soon i will post a pix of the OLD resistors they used years ago,,,that never went bad!!
maybe we can find a way to do a better fix!
oh,,?if one, but not 2 it almost has to be a connector,or sw contact,all res are good if it works in lowest mode
when u find the pix of melted conn youll see what i mean!

Well the blower motor resistor is electronic on the H3 and is located under the passenger side of the dash. It is white with 2 phillip screws holding it in. It has a 5 wire connector and is easy to spot. Well mine completely dropped dead today and I picked one up at the local autoparts store for $48. It is called the AC blower power module. Just for your info.
