Actuator switch or Transfer Case
\015 How do I tell if the actuator switch or the transfer case is bad? I am going to look at a 95 Cheyenne & the guy said it wont shift into 4WD & doesn't know why.\015
The acuator switch is soo easy to replace for about 15-20$ just replace that first, also if its the acuator switch the light down at the shift bow will NOT light up. If it were your t-case normally it would light up but nothing would happen

I have a 1998 GMC K2500. When I push the 4x4 selector into 4hi or 4lo, the indicator just blinks. I can eventually get it to lock in by switching it back & forth several times. I have replaced the switch, front axle actuator & transfer case actuator within the past year. I just replaced the transfer case motor thinking that might be it, but no difference. What's left??

I just switched out the transfer case (NP 241 C) and It still wont go into 4wd. The vacum line to the transfer case is capped off and always has been. the only thing left is the transfer case switch or the actuator. Can I remove the acctuator fron the diferential and check to see if its working ok or does it ground to the diferential?
Just replace the actuator in the front differential, they commonly go bad, I hope you needed the transfer case anyway. ... 1989 Chevrolet Silverado 2500
4wd light flashes and have replaced the front actuator switch and the encoder(transfer case motor) and nothing has changed. it sounds like it wants to kick in but never fully engages. I have had people on here tell me it could be the tccm, dash switch, or transfer case switch. i also scanned it with a AutoXray 2000 machine and it came back with a P0700 (transmission control system malfunction). But when i had my transmission rebuilt i found this code and took it back and they couldn't find the c

I have a 2000 Chevy Silverado 1500 5.3L engine, automatic transmission, automatic transfer case. It has the push button 4wd system. My service 4wd light is on, and i cant figure out what the problem is. I read that the transfer case control switch will often go out and cause this, so i replaced it. no luck. I rebuilt my front differential to find two pitted bearings, meanwhile i replaced the actuator. still no luck. Then i decided it must be the transfer case control motor, which mounts t
Hello rwells.The transfer case shift motor is the usual suspect in most 4x4 engagement failures.Inside the shift motor there is a position sensor that signals the module where it is.Because this is a digital signal it can get "confu ... 2000 Chevrolet Silverado 1500

Sure sounds like the vacuum switch is not working properly. You have done exactly what I would have done, start with the actuator(most common problem) and go from there. If your not getting the vacuum , then most likely the vacuum switch is your prob ... 1997 GMC Sonoma

I have a 96 k1500 4x4 pickup. My 4x4 isnt working properly. The 2hi light never lights up even though it is in 2hi. The transfer case sill lock in low gear when activated, but the front axle will not lock in. The front axle will not lock in for 4hi or 4lo unless you pull the actuator switch on the top drivers side of the transfer case and manually activate it, then it engages, but the lights still don't light up accordingly. What do you think could be the problem and what should I look at d

Ok i replaced all the vacumm lines on my s10 and followed a diagram i got off the net as for routing them, and replaced my vacuum switch because it was broken, my actuator under the battery is still good and when the cable for the front diff is pulled by hand it engages, every thing shifts fine in the transfer case also, so why is my four wheel drive still not engaging on its own? it is a manual trans case, it seems like its still not pulling vacuum, is there any advice on how i could fix that?

My 01 Trooper had problems with the TOD starting last winter. When the switch on the dash is engaged the TOD indicator flashes continually at 4hz but the check lite does not come on. I have vacuum at the actuator but no way to measure it. I locked the actuator in the 4wd position using a 10mm bolt as described in one of the 4wd forums. I have manual hubs installed also. My problem now is that the transfer case is apparently turning in the 2wd mode. The TOD indicator blinks no matter what 4wd mod
We have a 1998 Trooper that had the same problem. The fix was an electronic switch for the 4WD - a vacuum sensor - on the front axle that just plugs in. You can see it - if you look under the car from the front, it's mounted in the middle of the fr ... 1998 Isuzu Trooper
