Question i have a 03 gmc k1500hd, w/ quadrasteer. i have a service 4wd that shows on my readout. at start up all the lights on the push buttons come on, then go out right after start up. a code p1875 has been read. i have replaced push button switch, i then was told the sensor on the t/case, i then replaced, still nothing. please help! russ.
Answer Hi
I would advice you, so you dont spend anymore money on unneeded replacement of expensive parts.
It is a pretty technical diagnosis for this code, and the switch and or encoder motor had NOTHING to do with this code.
Therefore, I would advise taking it to a GOOD electrical repair shop, or dealership and have it properly diagnosed.
Thats my advice.
I Hope it helps

PS IF you happen to want the diagnosis for this code, I'll be happy to send it along, just ASK.
