problems with 4x4 and door locks

[yukonaetahoe]

I have a 95 yukon, i went to the snow last year and was using my 4x4 in a slow patch of snow, then we were back on the road and switched it back to 2wd, eventually i hit a second pathc of snow and kicke din the 4x4, but it would not..... and since then i have not used it because i think its going to be something expensive. i noticed the fuse was blown, so i put in a new one and when i shift to 4x4 is blows every single time. has anyone had this problem and any advice? thank you.


my door locks dont work either, i tried my switch on another truck and it worked. it wont work with my alarm or doig it manually. but when i press it i can hear a click from underneath were the steering wheel is. also anyone have this problem? any advice??

Bro, I've got nothing for you. Sorry.....

they may have crossed something with the alarm if its not factory (and i doubt it is on a 95) have you checked the wiring from the transfer case to the cab?

they might not be related at all. maybe just a coincidence they stopped working at the same time.

I'm not sure about the door locks, but I think I can help you with the 4x4. In the 95 yukon/tahoe there is an actuator in the front differential that is notorious for going bad. There may be a short in the actuator itself and that may be causing your fuse to blow. I think a new actuator will cost you about $60-$70 on ebay and can easily be replaced in your driveway. Hope that helps. btw the actuator sticks out of the differential on the passenger side

sounds like a dead relay for the door locks. if the fuse is good id find that relay.

My door locks do the exact same thing, started yesterday. pull the cover off the fuse panel on the driver side of the dash, look at the row of fuses closest to the firewall, just past that row, you will see two larger rectangular metal 30 amp fuses, simply touch the top one, i was looking around trying to fix my locking issue yesterday, and when I touched that fuse it literally burnt the skin off my finger, I disconnected the battery, and put a temp probe on it, and 5 minutes after i disconnected the battery, the temp was 191(f) degrees I don't know the culprit, but this is supposed to be your fuse for the door locks, but even with it removed the relay under the dash for the locks will still click when the button is pressed in either direction.

i cant seem to find any relay other then the two chrome fuses to the lef tof the fuse box. and like garrenchildres said it just makes a clicking noise.

does anyone know where this "relay" is located because i cant seem to find it anywere and i already changed the two fuses on the side of the door and still no love. i dont see how it would be the door actuator since both dorrs wont work at all unless i manually move the lock up and down.
