If girlfriend vacuum heat is un hooked or broke your 4x4 light would not which (at least when mine damaged it didn"t) the was likewise talking about your heater controls no workung right and also if you room standing in prior of her truck, on the passenger next by your engine oil dipstick over there is a vaccum line the goes under by it beside the entry manifold. There will certainly be a tee with a black plastic line going to it native the firewall. Coming turn off the tee there will certainly be a white plastic line coming native it the goes down to the height of your move case. If you follow the front drive shaft back from the front you will se the it connects to the transfer case. Wherein that white line connects to is one actuator switch v a square rubber plug with for plastic line coming the end from it. (Blue, green, white and red) the blue and red, those vaccum present going to the actuator top top the front axle. The ones in the pic... The white is the supply and also the eco-friendly one come up next to the trans and also comes up the end on the motorists side by the brake booster reservoir alongside the intake and also has a check valve ont the finish of it. If any of those space crack or damaged your cruse control wont save speed and your heater as soon as you excellerate will readjust to defrost or to vent... However as quickly as you let turn off the pedal say if you has actually it set to heat, it would go back. Ns would inspect those lines and look in ~ the front drive shaft and also go indigenous there... Sorry for the book...
