I have a 95 Blazer (4.3L V6) that won't go into 4WD. When I press the push button for 4 high or 4 low, both lights will blink a couple times and then both lights will come on and it won't kick into 4WD. Any suggestions?

 

have you checked the actuator?

 

Thanks for your suggestion Lrain88, I checked the actuator and noticed that the vacuum line coming off it was cut in 2 pieces (it was melted- probably touched the engine or exhaust). After tracing the line I noticed another break in another line coming off the vacuum plug on top of the transfer case. I replaced both lines and found out that the electrical plug, which is a screw in plug, was not connected either. Needless to say, now I have 4Wd again. Thanks!

 

no problem glad to help and glad you have some 4x4 blazer power!
