Hello everyone, I have a 96' chevy suburban. To start with, the fwd buttons on the dash started to blink when i would try to engage the fwd. It souded like a relay under the dash was clicking struggling to engage. now the fwd lights on the buttons will not turn on and the fwd will not engage. I have had problems with my 95' tahoe before and just replaced the actuator on the front axle and it sovled the problem. I have replaced the actuator in this 96' and it had no effect "still not working". I noticed that it does have a electric vacuum switch that screws in on top of the transfer case. I am thinking this may be the problem? Of course i checked all fuses before all of this, lol. Thanks for anyones input. PS, I cant believe that chevy switched from a all steel actuator to an all plastic one in 96!!
