I know Final Stage Resistor Issues are all over this and other boards. My problem seems bigger and I really need some help! Here is the history:

1. Fan stopped a month ago. Replaced final stage - worked for about a week then out again.
2. Replace final stage again. Again worked for a week then stopped.
3. During that week when it worked - got a squeaking, rattle sound from the fan.

My hypothesis is the blower fan for the climate control has some problem (out of balance, shorted out?) that is causing a power surge to the final stage which is blowing it out after a week.

Any ideas? Any DIY links to replacing the A/C climate fan?

Many Thanks!
