hi there, I am the not so happy owner of a gmc jimmy 97, I was having plenty of trouble with the truck's front wipers, I took the little motor out, disassembled it and inspected all the parts. I found that the wire harness attaches to a socket on the control module, for some reason, either be vibrations or movement when you do something close by; the solder on the module's pins breaks, causing an erratic performance, since I have the tools, I just resoldered the pins, taking care to make a better job than those guys at the assembly plants, and had no problems after. Still however, whenever I do anything close by, I will pull off the harness so as to not disturb the module's guts, annoying at some point, but beats paying for a new motor!
#491 of 535 Metri-Pack connector
Apr 10, 2009 (4:31 am)
I recently purchased two Metri-Pack terminal removal tools (Delphi 12094430 and 12094429) in order to remove the Metri-Pack terminals from the Metri-Pack plastic connectors. The clip on the Metri-Pack plastic connector on my alternator was damage by someone with a "screwdriver removal tool" and normal vibration and wind from the fan can blow the connector off the alternator. A new 4-way Metri-Pack plastic connector (AC Delco PT1929 or GM-88860484) for the alternator cost $15. That is expensive for a 50 cent part but nothing else will do and General Motors knows it.

i have a 1995 jimmy which i took to a mecanic to get the head gastets done. i was told i had a colasped piston. now can anyone tell me what that means and what are the causes of this. we have a 2003 van with the same motor and i don,t want it to happen to it. Thanks

It means that your piston has become deformed due to excessive heating which, in turn, was caused by your head gasket problem.

Well, the problem you encountered is not exclusive to Blazers. It is a well documented problem that GM ran into by not securing the harness that plugs onto the connector you re-soldered (which is the exact correct repair - Good job!). I have seen it on Blazers, trucks, vans, you name it. It is caused by the constant vibration of the wiring harness being transmitted into the connector and fracturing the solder. Lots of new control boards were installed just for this reason.
#495 of 535 Converting my spare tire mount
Apr 14, 2009 (6:24 am)
I have a 2000 Chevy Blazer 4X4
I was thinking about converting my rear mounted spare tire to be inside of my truck, anyone know if there is a way to do this?

Well, the mounts for a 2dr *might* fit, but you will be left with holes in the body and a big loss of interior space. While I do like the smoother lines of an interior (or better still, underneath) spare tire, that full size spare takes up a lot of room.
I have wondered why they didn't put a small spare in there. I am supposing it has something to do with that little doughnut being completely useless in an off road flat tire scenerio.
Then again, with four inches of ground clearance, my xTreme sees pavement only!

My 98 did it and my 02 does it. A guy drove by my in front of the gym and his was doing it............I think they all do it. Someone told me that the fan clutch is engaging..I don't know other than they all do it.

All of the 4.3L engines do it, not just the Blazers. It is the fan clutch. No slippage when cold at startup, but will disengage within a minute or two. If it continues to roar, turn off the engine and see if you can move the fan by hand. If you can move the fan with only a bit of resistance, your good. If it doesn't turn, or takes a hard effort to turn, it is probably time for a new fan clutch. Running with a locked up clutch will affect your gas mileage, so it is worth changing.

I've spent days reading the forum here trying to figure out my truck,,,symptons are as follows...takes 3 attemps to start the truck when cold...just cranks until I try three different times...at low rpms the engine misses bad..If I floor the pedel it runs fine...on highway when I set cruise...engine starts to jump and miss..bad.
sometimes the SELight comes on...other time it doesn't I've taken it to 3 mechanics....no one can figure it out...Have gotten two codes...MAPS sensor bad...Replaced...fuel pump, dist, cap rotor....plugs...wires....crank sensor...cam sensor..ignition lock assembly...One mech already told me the CAT was fine..
Any help would be appreicated as I am at a loss...Planning on giving this car to my kid next month but it has to run right first...thanks again for any ideas.... oh I forgot...replaced the computer...also...got a code once that says engine is -7 degree on timing...can't adjust since the bracket is notched and holds dist in postion...also...sometimes the cruise works..sometimes doesn't...and sometimes only one side of the speakers play...help please.....
