hubs locked
new transfer case motor the second one
first worked one time then quit
new hasnt worked at all
can the switch in the dash be bad?
can you manually engage 4wd?

 

Did you try the transfercase in 4x4 while the transmission was in neutral?

When you take the **** off the switch the green light stays by 2wd no matter if the switch is set to 4wd or 4lo

tried hubs in auto and lock

can the switch go bad

I pulled all the fuses

the vacum comes on and runs when keys turned on.

 

trying to go to lake and boat ramp reallys steep and can not pull boat up it without 4wd, rear tires just spin...

 

If your vacuum pump runs all the time when you turn on your key, I'd say you have a leak somewheres that's keeping the transfercase or axle from engaging. I'm not 100% sure, but I think that switch on the dash is a vacuum switch, not electrical.

 

i have seen the switch go bad and the vacume control solinoid.stick a vacume gauge on the line that goes to the hubs and see if theres any.

 

If your hubs are locking then you don't have a vacuum problem (most evident by the vetilation going to defrost for a couple of minutes when switching between 2wd and 4wd). If your transfer case is not engaging, then it's electrical or somewhere in that path.

I am not overly familiar with the '05-up, but I do know that with the upgraded suspension, the ESOF got beefier for the hubs and you are less likely to have hub locking issues than I am.

My electrical side goes from my switch, to a 4x4 control module to the transfer case. I'm no mechanic, but going what you posted in #1 and #3, I would check the switch and the control module (I think it's under the dash). I would make sure the switch is good and there's a good connection to the control module (unplug it and spray some electrical contact cleaner in there too) and try it again before emptying your wallet again. Anything's a possibility, but I would attack the easy stuff you can do (or fix with minimal $$$). With your indication stayin at 2wd, I would think that it would be somewhere in the switch, control module or the wiring (connections) in between. That's basing my assumption that the indicator light comes off the module and not something sent from the transfer case. Since your transfer case connector is open to the elements, it probably wouldn't hurt to pull that one, check the pins and clean it out too just to make sure it's making good contact too.

I would tend to lean towards a control function instead of the t-case or motor since your light doesn't go to 4wd (sounds like the signal isn't getting sent to engage the t-case, especially if you don't hear the 'clunk' of it engaging). I could be wrong since I haven't experienced an electrical problem yet (I'm an expert at the vacuum side though ). Sorry it's so generic, hopefully somebody else will chime in with more specific info for you. If nothing else, it's a bump for ya.

With the ESOF system, I don't know of any way to manually engage the transfer case, only the hubs.

 

it did do that previously
it was most annoying thing but then it just cleared up..

 

switch the esof relays.
If it works,you need a new relay.

 

where are the esof relays located?

 

took to dealer electrical and hubs leaking.
