99 chev blazer should have an electric motor not a vac switch...Is your controll on the dash a switch you turn.. or on the floor you shift ??

well make sure it is the tranfercase because if it was u wouldent have 4wd and u wouldent be able to drive it but it would be cheper to rebuild it but make sure first because some people are just out for your money good luck
SOURCE: Transfer case leak
You mean between the case halves? It is just silicon, no gasket. These are good for the pump wearing a hole in the rear housing and leaking oil. The cure for it is a new rear housing and a piece called a case saver that keeps the pump from doing it again. Taking the transfer case apart to fix it is easy, I can tell you how to do it.

Having the same exact problem but with my 1999 escalade. Thought it was the actuator bought a new one installed it transfer case would engage but front end wouldnt lock. Took it out of housing left it plugged in got a friend to go through all the 4wd for me and the plunger never moved out the actuator. Checked my wiring harness which is a four prong ann it had one hot prong like it is suppose to. Traced wires even replaced dash switch same problem. Taking it to local dealership tom to have it checked for codes. I was told it could be the transfercase actuator even though its workin that actuator is what sends power to the front to engage the actuator to lock the differential.

Well the one doesn't have a tag. Both front and rear drive shafts go in. Just the connection between the transmission and transfer case doesn't. Are they difficult to take apart and put back together?
