I did mine about a month ago with OEM Acura resistor pack (30$)and it’s still running. Did you do yours with Radio Shack resistors as “jgn77” suggested?
yea i did
Update. Last week the resistor for the next to high setting went out effectivly shutting down all speeds except for high. I replaced the resistor again and not a week later the same resistor went out again. I can only speculate that the reason that one keeps going out is that it bears a full load on all settings except high. So I have come to the conclusion that I should go to the dealer bite the bullet. Sorry for anyone that has had undo aggravation due to my suggestion. It was fun to try it though and you don’t win them all.
I know that this is an old thread, but I thought I’d give it a shot. Only settings 3 and 4 were working on my integra. So I replaced the 2 highest resistors with the .47ohm 5 watt resistor, and left the 1.0 ohm resistor attached. So far so good, hopefully this works for a while. I’ll keep everyone posted.
DO NOT DO THIS MOD!
I know this is an old thread, but just in case you come across this through a search like I did, there should be a safety warning of DO NOT DO THIS MOD!
There is a reason why the resistor pack uses nichrome wirewound resistors instead of your common variety Radio Shack carbon composition resistors.

LO - M1 = 2.2 Ohms
M1 - M2 = 1.5 or 1.6 Ohms (Edited)
M2 - HI = 1.0 Ohms

At high speed, power is going directly to the motor.
At M2 speed, with 12 volts going through, you can expect around 144 watts going through that 1.0 Ohm resistor.
At M1 speed, about 55 watts through the 1.0 and 1.6 (2.6 Ohms).
At LO speed, about 30 watts through all three (4.8 Ohms).
That is way above the 1/4 watt and even 5 watt resistor. You’re running a high risk of burning up the resistors.
Here is what can happen when you overload 1/4 watt resistors:

FIRE!
The nichrome wirewound resistors can handle the power. Those wires get really hot, probably why they are placed inside the blower housing, and probably why you have a 30a fuse for them.
Nichrome is also same wire used for heating in hair dryers.
Don’t be that guy who sets his car on fire trying to save $30. 
Someone sticky this please.
This thread is jesus.
