NO 4WD after frame swap.

so I picked up my truck after a frame swap 1.5 weeks ago.
Battery died after I got it home,charged it up & it's fine. They must have drained while working on it.
Went to drive up my hill in 4wd,& all I get is a blinking light.
Worked fine before the swap.
Tried it in reverse,4 lo,no go.
Any ideas on what I could try at home to fix?

 

Any loose wires hanging underneath? They may have forgotten to plug something back in.

 

Checked plug @ front dif. All looks connected.
Won't even go into 4 high.
I'm being told by dealer that the 4wd actuator "just goes" on these trucks.
I'm going to try tapping on the actuator with a brass hammer.

 

Bullshit. Tell them you used it the day before it went in for frame swap and worked just fine. Complain until they fix it for free.

 

Supposed to be in N for 4lo

 

The actuator is vaccum assisted, check to make sure they put the vac line back on.

check this thread out it probably the contact points. I had mine solder.

 

Not in any gear would be considered N in a manual. I had an auto so I may be incorrect for a manual 4lo procedure

 

ADD hasnt been vacuum assisted since like late 90's


OP take it back to the dealer, it worked before you brought it in it should work after plain and freaking simple. Make them own up to it.

 

This..

 

I see, your problem is slightly different. I had nothing not even blinking light. in your case it sounds like transfer case is kicking in just not finishing.
Start at the front actuator (front diff ADD). Unbolt that thing and check if it moves when you switch to 4HI
Toyota in their infinite wisdom did not solder electrical motor that locks front, so maybe after they dropped front diff on the floor connection is broken.

 

Im not going to mess with it,since its the dealers fault.
I have an appt on wednesday.
We will see what they do.

 

Being a mechanic (not auto), I will say that a mechanical failure isn't out of the realm of possibilities.

However, sending it home and saying all is well isn't acceptable.

don't be a dick when you talk to them, but be firm. Preferably in person with a service manager, rather than over the phone and with a service writer. Don't expect any pity for the battery since its been almost 2 weeks, but do mention it.

 

I just got my truck back.
It was the front dif actuator.
They put a new one in.
No charge.

 

If anyone is looking for a good dealer to bring your truck to,
I would recco freedom Toyota in Harrisburg,pa.
