General ChatChat about all things Blazer (and related vehicles). Off-topic stuff should be in the lounge, and all mechanical problems should be posted in the proper forum.
the controller has 2 fan power wires so I used them as trigger wires on separate relays and put a master switch on the main power for the controller. I read that the draw from the intrepid fans is something like 70 amps so I got a pair of 80 amp relays just to be safe
Did find out why I was breaking the stock fans..broken motor mount on the passenger side. Upgraded to interlocking ones from Energy Suspension.
Found out that a case relearn can't be done when you have a P300 code. Started off chasing a misfire on #6 which became a general misfire after moving the #1 wire off of the header and fixing a couple vacuum leaks.
Got help removing the broken bolt from changing the valve cover gasket
Found the ignition coil was failing and the cap and rotor looked bad after 30k miles so replaced those..then the case relearn was done,
Truck runs much better now.
Got stuck behind another vehicle at the alignment shop.. The tech tore into a car on the alignment rack instead of moving so no alignments got done after 10:30 am.
I will get it done Monday just in time for my trip on Thursday which will include a run up the Morrison Jeep Trail in Wyoming.
Personally, I haven't done anything to it in a while. Just recently though my son changed out the ported vacuum switch that we are being told is no longer available. He ended up pulling one off of a parts 2wd Blazer which we bought some time back with no title. He also pulled the dash panel out of his '85 4wd S10 Blazer with intentions of switching the instrument cluster for the cluster out of the '85 2wd S10 Blazer so he'd have the tachometer. I'm not sure how feasible it is but he thinks he knows what he's doing. (Not that I doubt him... I just doubt it. lol)
