Hello...

My wife's car is a 1999 Pontiac Grand Prix.

She gradually lost all of her fan settings to the fan... with the last being 4 which died a week ago.

From what I've read, it seems this may possibly be a bad resistor relay? if so, how difficult would it be for me to replace?

How about position 5 - High?

Troubleshooting or replacing the blower motor resistor or fan is not that difficult. High probability it is the resistor. But to be sure it's always a good idea to bench test the blower motor by jumping 12 volts to it just to make sure if its OK. If blower turns its probably a resistor.

Here's a pic with the blower motor removed and to the back is the resistor. This is applicable only if you have a manual control HVAC system and not the digital climate control.

There are 3 bolts that hold the blower motor up to the housing. Good luck!
