My 1997 GMC Sierra lights for 4hi and 4lo blink when i push the 4hi button and then goes back into 2hi. but when i push 4lo it locks in and works fine. I tried changing the 4wd motor on the transfer c

THE TRANSFER CASE MOTOR IS ONLY FOR 4WD LOW. That would have never been the problem as soon as you confirmed it shifted into 4wd Low. 2wd and 4 Hi work off of vacuum. You may have one or two issues. A vacuum leak up by the front axle that engages the 4wd HI or the sensors on the transfer case.

2001 Ford Ranger, 4wd doesn't work. The 4wd light on dash flashes 10 times about every two minutes.

There is obviously an issue with the transfer case. I doubt anything mechanical is wrong. Take it to your nearest autozone they can scan the code and give you a general idea of what to look for. 99.9% of the time they can help point you in the right direction. I had a smiliar problem with my exploder but mine was simply a shorted wire in the 4x4 high low selector switch assembly.

My 4WD is not working. Whether I put the selector

Operationally vacuum holds the IWE ( Integrated Wheel Ends ) out, and once vac is removed the spring engages the IWE.

Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc )
Key on, engage 4x4 and try to turn the front drive shaft.
If it turns it is a problem with the transfer case.
If it doesn't it is a front axle engagement problem.

- If the front drive shaft does not turn :
Shut of the truck ( still jacked up, and supported ) remove the vac lines from the IWE. The spring should push the gears in, without the vac line on.
Check the vent line ( tube that is routed into the engine compartment with nothing attached to it ), for blockages.
If the vent line is clear, and with the vac lines off the IWE should be engaged ( both front wheels locked ).
If they lock, the problem is with the IWE solenoid not shutting off vacuum to the IWEs. There is a TSB on the 2004-2006 IWE solenoids, a newer revision has been made, and used from 2007 and newer MYs.

Here is a block diagram of the IWE system

Here is a link to the TSB for the IWE solenoid in PDF format
