Help 4wd not working

Hi the title says it im having trouble with my 4wd I press the button and nothing happens i tryed seeing if its a fuse and it was poping the 4wd fuse i tryed looking up what might be wrong and found the actuators on the transfercase and front diff go bad if anyone can help me please i hate having 2wd in snow oh ya i unplugged the plug near the driveline and it didnt pop the fuse andy 4hi and 4low on the gauge cluster were flashing then i plugged the plug back in and it blew the fuse again again any help would be great and how to test before i go and buy an actuator

 

That sure makes it sound like a short or ground within the transfer case actuator, or it's seized up . I haven't had reason to mess with one, but some of the Tacoma guys on TW had success disassembling and cleaning them out and cleaning the contacts. Might be worth a shot.

 

Do you have any error codes?

 

I too have heard of this happening. It gets water and dirt in there and corrodes the connections.

 

Its all good for now had an electrician buddy look at it and he put a breaker in my truck between the fuse now it works guess something is drawing to much power once in awhile

 

Ya hopefully it stays working now to figure out y my fog lights dont work and when i press the button it turns on my high beams and not my fog lights the lights in the bumper

 

I have the same problem if anyone knows the solution I would greatly appreciate it.

 

you probably all figured this out already but the same thing happened to my 2002 tundra. The 4wd button would just flash. I took it to my Toyota dealer and they told me that the it was the transfer case actuator switch that had corroded. My two older sisters drove my truck for 4 years and were scared to drive in snow or anything other than regular pavement so the actuator switch got corroded from not moving in many years. I had to take it in and get the actuator switch replaced which is a switch that engages the transfer case. since my tundra just has a button and not a physical lever to put it in 4wd. It ended up being around $2500 and took about 3 days. It works now and the told me that I need to put it into 4wd at least once a month for just a little bit to keep that actuator switch active and avoid corrosion.

 

Ya it just pops the fuse once in awhile i just said screw it and bout a crap ton of 20 amp fuses and replace it when the fuse pops

 

My 2000 had the actuator go out. Tranny shop said $3500 to tear it down and replace it. There's a retainer on the inside of the t case. You have to take it all apart. Toyota changed the design like eight times in the first two years. I got a used one out of an 03 for $300.00 from Yota Jim's in Denver with a 90 Day warranty. It worked flawlessly until I sold the truck last year.
