The vehicle has had the indicator light for HDC on since we did a kludge job hardwiring horn to battery and installing a separate switch on the dash. The extra wire is a little tight against the other cable bundles up under the steering wheel, but it strikes me as unlikely as to that being the cause. No amount of fiddling with the actual HDC button on the gear-stick has worked to switch the mode off... Any advice on possible causes or fixes to allow selection of 4WD when required would be much appreciated. Thanks in advance.

After reading some of the fixes here and on other forums,i bought a vacuum actuator and a transfer case switch.My mechanic came to fit these today,replaced the actuator and it didnt do anything.Turned out the old one was o.k..He couldnt find where the case switch went ,so he started tracing the vacuum pipes.
Guess what? he found not one ,but two broken pipes.he replaced/shortened these and hey presto,i now have 2,4 hi,4low and auto all working again.
It may be worth checking the vacumm pipes before buying other parts.
Just a thought...........

this problem is caused by the rotating contact under the steering wheel that connects the horn (and airbag) button to the steering column wiring harness, this contact is commonly called the clock-spring ribbon contact. WARNING! Before u replace this u must remove the wheel and the airbag module on the wheel, the airbag must be disarmed, the easiest way is to disconnect the battery 30 minutes prior to starting work, this always ample time for the system control circuit capacitors to drain down.

If the horn works with direct connection, and fuse, relay, and circuit breaker are all good, it's the switch in the steering wheel. If it is anything like the chrysler auto's, the switch and the air bag module is all one unit, can't replace just the switch, the whole thing, and it's about $700 to $800 for those units, at least it is here, and can only get them at a dealer.

try putting in nuetral and then shift into high gear . if still does not work sounds like the 4x4 acctuator is bad

i had a '71 dodge with three-on-the-tree that experienced binding and the only way to fix it is to replace worn parts. as for the lights, find out which connetor supplies power. perhaps it is faulty or loose. also, there may be a separate fuse located on or near the instument cluster specifically for that application.
