No it is not going to. If it does then why did they use the four wires in the first place? Duh!

If you cap the ground wire nada will work - if you cap one of the wires going to a motor winding, that speed will not work.

bad motor "burned out"
get a new one

I can offer resources:

1) Test switch that was removed, and test for hot connection to narrow down options.

What speed was fan stuck in when switch was removed? Let's say medium speed.
Which connection at fan is hot? Use voltage tester to find hot connection at fan, and match that up with wire-color on switch that was removed.
One and only one wire on 3-speed fan switch connects to hot. And the hot wire is the only wire that connects to each other wire as switch cycles through pull-chain sequence. All pull chain switches follow same sequence: off, low, medium, high.
Let's say old switch was stuck in medium, and you know which color wire connects to hot.
Test switch with continuity tester to see which wire(s) have continuity with hot wire: some switches, it will be 2 wires, and other switches it will be 1 wire. Match where wire(s) were connected, and map that to tests on new switch.

2) Open following link for illustrations and some other links.

Old switch and new switch have to be compared using multi-meter or continuity tester.
Each 3-speed switch has identical pull-chain sequence: off-high-medium-low.
Each 3-speed switch has only one wire that connects to Hot wire.
But the other three wires can vary.
For example connect power to switch Hot wire. Let's say switch is in off position. Pull chain once for high speed and power might flow to just one wire, or it might flow to two wires, depending on the switch.
Pull chain again for medium speed, and power might flow to just one wire, or it might flow to two different wires.
Pull chain again for low speed, and power usually flows to just one wire.

Easiest place to start is to find which wire is Hot.
Only one wire connects to Hot power.
That same wire on the new 3-speed switch will connect to all other wires. When testing, only one wire connects to all other wires.
Once hot wire is determined.
Then test which sequence of wires receives power each time chain is pulled.
Repeat same test on old switch.
Note how old switch was connected. And then map the change-over to new switch.

On a 3 speed switch you usually have 4 terminals, and they are marked L1, 1, 2 and 3.
L1 which is line voltage from the electrical cord or wall plug, #1 low speed usually a red wire from motor, #2 medium speed usually a blue wire from the motor and #3 high speed usually a black wire from the motor. That is if the fan is low,medium and high, if it says high, medium and low then reverse #1, #2 and #3
