Since the ECU controls the fans on a 2g, your ECU may be bad (eg. leaking capacitors). As to which wire is hot, it matters much whether you have the two stock 3 speed fans (yes they are actually 3 speeds - not 2) and wiring or some aftermarket single speed fans which may have changed the wiring.
If stock:
(Note: the wire names are my own where hi/lo corresponds to the fan relay's hi/low name.)
Passenger side (radiator) fan wires on harness side of connector are:
lo positive (+12V) = white/black (white with black stripe)
lo negative (goes to ground) = black
hi positive (+12V) = white/blue
hi negative (goes to ground on M/T, switched on/off to ground by the 5th radiator fan relay LO2 on A/T) = blue/green
Driver side (A/C) fan wires on harness side of connector are:
lo positive (+12V) = blue
lo negative (goes to ground) = blue/black
hi positive (+12V) = blue/white
hi negative (goes to ground) = black

Interesting note: The stock turbo 2g fans have 3 speeds (not counting off) but only 2 speeds are used (why many people call them or think they are a two speed fan). M/T uses off, medium, and high on the radiator fan. A/T uses off, low, and high on the radiator fan. Both use off, medium, and high on the A/C fan. The ECU controls the speeds based on engine water temp, vehicle speed, and whether A/C is on/off (

The speeds are not obtained by voltage on a unique specific wire pair but rather voltage on wire combinations. Thus my wire names and their relay names are somewhat misleading. Low speed is voltage on one positive wire (either lo positive or hi positive) and ground on one negative wire (either lo negative or hi negative) although most 2g dsm's use lo positive and lo negative. Medium speed is either voltage on two positive wires and ground on one negative wire OR voltage on one positive wire and ground on two negative wires (most 2g dsm's use the latter). High speed is voltage on both positive wires and ground on both negative wires.
When people substitute a single speed after market fan they tie the positives together and the negatives together so it is always either off or on high speed (fans running all the time? - DSM Forums).
