Thanks Goldsmi for the info. I found those transistors on eBay from out of China, took about a week to get them. Cost, $7.50 for two. There are two mounted in that assembly and it took a bit of desoldering to get them out but once replaced and reinstalled the blower works like a charm. Thanks for helping me save a tidy sum of money.

 

My pacifca is doing same thing.. Thinks its alternator.. Been reading alot of isssues with this problem.
