When it comes to ease of repair, a serpentine belt replacement is hands down the faster and easier of the two. All that is required is breaker bar and a new belt, at least for my system. No need to bring out the tool box to loosen component bolts or remove belts to replace another belt followed...
The benefits include:
1. Higher flowing water pump for better cooling performance
2. More responsive fan clutch
3. Fan moves so much more air over the engine now
4. Serpentine belts last longer than V-belts
5. No belt squealing because of the tensioner
6. If you have ever had to change...
I have two used optima batteries with less than 6,000 miles on them in three years. I had these tested at the local O'reillys a week or so ago. Batteries tested good (see pictures). I tried the craigslist route but it seems only scammers and low ballers want to send me offers. I'm asking $100...
Got rid of the ground at 87a on both relays and everything works perfectly. I can say the window does go up and down faster but not by much. I'm talking only fractions of a second faster. I am using junk yard parts too so maybe the motor is all worn out. I'll have to see if a newer motor...
Well with re-arranging my pins to the above wiring I am able to get the harness installed and properly grounded and hooked up to power without burning up any fusible link! Progress is progress. Ok, so now that nothing is smoking right away I turn the key and still no smoke. I'm 2 for 2! I push...
So this should be how things are wired up
Pin 30 12V source in (junction block)
Pin 85 Ground
Pin 86 12V from the switch (up or down from the window switch)
Pin 87 12V to the window motor (up or down)
Pin 87a Ground
I'm doing some reading here on how relays work: http://www.rattlebars.com/avalanche/relay_basics.html

Ok, I think I have this figured out. If you look on the wiring for the door power windows you'll see that each switch has a ground wire that connects to the main power window harness which is grounded to the bus bar under the dash. On the rear power motor the switch is not grounded. The only...
Replaced the pieces of the harness that got all melty and tried again after swapping pins 85 and 86 in the relay mount. Fusible link burnt up again. Glad I added some quick disconnects this time in case the link burned up again. This time it was only one wire that got hot and melted the relay...
