problem #2

Sierra 2500 LX 6.6L

  • Automatic transmission
  • 200,000 miles

blower wire heats up which makes heat and air intermittent

While running my ac or heater it would become intermittent. Under the glove box, I moved a thick wire that was too hot to hold on to but it would ether start or stop the blower from working. Not sure if there was a recall on this item. I also have a "service air bag" light that stays on all the time while the truck is running. I love my truck but electrical issues are starting to drive me crazy!

Sierra 2500 SLE 6.6L

  • Automatic transmission

The spade terminal end connectors on the pigtail look like they were made in china like everything else is these days. I took a pair of needle nose pliers and closed up the gap on the ends of the connectors so there was more metal to metal contact.
