lijkt een vaker voorkomed probleem:
http://www.truckforum.org/forums/4x4-tr ... oid-5.htmlAlleen mijn auto-technisch engels is niet zo goed. Ik weet eigenlijk niet eens hoe de delen er allemaal uitzien. Misschien kan iemand me hier een tip geven.
Had no 4wd in high or low range.
1st checked fuse and it was good
Next checked that front drive shaft was not able to be turned while in 4wd.
Then pulled out selenoid from front axle and checked with a battery and it actuated so it was good (can probably skip if you read next step)
Then put shifter to 4wd and checked for voltage at selenoid plug and key on and had nothing
I then located my 2 pin connector to my 4wd switch located at the very top middle of the transfer case, that is where this post was very helpful. I put a jumper in the connector with selenoid hanging down in front. turned on key and the selenoid actuated. Problem found!!
I then removed the actuator with 7/8 wrench and tested with ohm meter. pushed in ball and no change in resistance meaning a bad switch.
I then went to 3 parts stores and all said would need to order. Part was 20 plus dollars at Auto zone and Advance auto . Under 7 bucks at O'riely's auto parts so I ordered it there.
Went home to put everything thing together temperarely til switch came in. I decided to spray some wd40 into the ball portion of the switch and actuate several times and it started clicking like a computer mouse. (thats the switch working) Ohmed it out and found the switch is now working. Closed circuit when ball is out and open when ball is pushed in.
Reinstalled switch and selenoid and my truck hasn't went into 4wd that easy in years. I used to think it was my linkage but probably a flakey switch all along.
Thats my story, hope this post can help people in the future. As far as testing the selenoid with a battery I was a bit nervous doing that as there is no polarity labeled. That step can be skipped if you just unplug the connector and check for 12v when in 4wd and key on. If its not getting the juice its a good chance its the switch. If you get 12v its probably the actuator.
