Mine did about two months ago. Typical symtom it is bad is that the blower only works in the highest speed. If you look at the schematic or if you look at the pack, you will see that there is a sort of overtemp protection loop on the pack that when hot it physically bends and breaks the circuit and stops the fan from running at all. I think I paid less than $20 for the pack.
That was the case on my car. The pack is above the gas pedal, under the dash, within inches of the bottom of the fan. It's quite easy to replace once you get on your knees with a flashlight a can see what you are trying to get at.
Good luck.
