If these are the hard plastic lines they are old and heat crack easy. If rubber the might be spongy from oil vapor. Either case replace them ONE AT A TIME.

4 wheel drive light flashes, wont lock in but transfer case seems to lock just not differential


You didn't specify which vehicle model you have, but most gm vehicles use vacuum to activate the 4wd system. Check all the vacuum lines you can locate for loose or disconnected line, cracked or gummy feeling lines. If you have the push button 4wd, listen for an audible click when you push the 4wd button. If you don't hear anything, the push button assembly may need replacing. If you did hear the click, then look under the battery tray for a loose vacuum line. Most gm 4wd problems are vacuum related.

WE have a 1984 AMC eagle with 258 six engine when we move the leaver over to 4x4 it's not going in four wheel drive, and diagrams or advice would be great. ...


well what was told is that my1984 eagle stationwagon, that if the 4x4 does not engage it is due to vacuum lines from the motor and the trany. these lines dry out and crack and vibration causes them to crack and the tight spots there in does not let you see or fix them to easy.

Three evap lights keep failing therefore I cannot get it inspected,,,What can be the problem?


Most likely it is a cracked or broken vacuum line in the evap system, or the evap solenoid is not working, once in a while it is the evap canister itself, but not very often. Also make sure the fuel cap is good and closed tightly and is the proper one for your vehicle. (a fuel cap that does not seal will cause an evap leak)

Check the vacuum lines and inspect them carefully.

This is a closed system and any vacuum leak that causes the evap system to loose vacuum, or not to hold a specified vacuum for a specified amount of time, will register as a data trouble code (DTC) and the malfunction indicator light (M.I.L.) (check engine light, or service engine soon light) will be turned on.
