Might be time for me to consider motor and trans swap/replacement; 323k miles- runs fine, but I'm starting to get nervous on longer trips...My last trip to Death Valley she got a little warm (once) and has been sipping some antifreeze lately. Honestly I have been searching for the next ride as...
Haha Yikes! yeah like I said earlier these Tahoes are one electronic controller from being perfect;)
Update: Ended up taking to my local shop...Tranny code and PS issue seem to be ghosts. But getting the 'o-ring' in the oil pan replaced today...so should be wheels up tomorrow for a good while.
First- Owned since day one, well cared for 295k. Tranny replaced about 100k ago.
Just recently noticed oil pressure sitting lower than usual...hovering around the 20psi (according the gauge). Historically this happens when low on oil, and a quick check and quart (or what is needed) is all that...
Update....even thou I changed the relay and multiple fuses....I am still getting the warning WTF!
It happens randomly, but also seems to happen when braking hard downhill...So I still think it could be a ground wire someplace.
What would be nice if the great engineers at GMC would have...
Yep I figured that out too! Here's another pic for location...But basically follow the fuel cell toward the front of the truck until the first subframe and its attached to it.
Ok...I MAY have found this little ******! ....the only thing is not 100% its the right relay, as the part# 25848909 doesn't line up to what I've read.........If so...its located inside of the frame rail right after the fuel cell, on on the subframe beam....trouble is the bolt heads are tucked...
Curious....If you ever found the position of the relay? I'm having the same issue of not finding the location.....
All the YT vids are for silverados or trucks which either locate on frame rail or under spare...nada on the Tahoe...
Thought I might have solved it this AM...since there are two pumps (ft and rr) with the rear one working, thought I could just switch the cabling and have a working washer for the front.....but NOPE different fittings! Dam!
Keep those suggestions rolling in;)
Ok....its not the motor...its not the fuses...what is it? I'm at a loss...
As a side note I'd just like to thank the GM engineers for their ability to over-engineer the placement of the motors and fittings so that it is nearly required to remove the front end to get at anything:)
thanks for the response....you make it sound ominous to get to the electrical connection with 'IF'...lol I hope thats not the case...but my previous experience has taught me the pretty much everything on the rig is a challenge to work on or get at;)
But I think your right, in that the pump is out...
