Four wheel drive lights flashing?

[72Blazerod]

Hi Guys,

I just recently purchased a 1995 L400 long wheel base, with the 2800cc turbo diesel. It only has about 118km on it. It drives great but last night I got in it to drive home and I noticed the 4x4 indicator on the dash had the front wheels flashing. It looked like it was telling me I was engaging the transfer case (or trying too). I played with the transfer case shift lever and made sure it was in 2wd and it seems to be, but the front wheel lights keep flashing on the dash. Any ideas what could be the cause?

Thanks

Flashing super select 4wd Green light most often occur when the front differential automatic disconnect is not engaging /dis-engaging when you select/deselect 4x4 drive.

Causes are:
- front differential sensor switch is damaged or faulty
- actuator rod/shaft jammed / seized (perhaps sand/mud/dirt)
- vacuum lines leak/popped off fittings
- vacuum solenoid valves (2no.) either maybe faulty
- electrical wiring connection issue (ecu/solenoids/switch)
- combination of the above.

If you have a flashing yellow light that is almost always a result of one or more faulty 4WD lever position switches on the transmission....and there are 5 of these bad boys on the tranny and in my experience only 2 of them can cause the Yellow Light to flash.....which is usually accompanied with an ABS warning light that won't go out.
Google 'SUPER SELECT, Flashing Green light'. The UK based sites have some great how-to-fix instructions.
