4 wheel drive problem
 

so i have a 2001 blazer and it runs great other than the fact my 4 wheel drive is messed up. i would love to take it mudding but if i push the button to go into 4wd it goes into it just fine but going back to 2wd it makes 3 clicks then stays in 4wd like its stuck. if someone maybe knows whats wrong please help.

How many buttons do you have on your dash switch?

i have 3. top is 2hi, below is, 4hi and then 4low

Three buttons means you have the NV233 transfer case. I would check for codes stored in the TCCM:
OBD2 NV233 Diagnostics

Also, have a look down through this thread:
NV233 No Mode Switch (ie. 2HI to 4HI)

alright thanks for the help ill take a look for sure.

so i did most of the things you told me to do but the problem still persists. i dont think it has anything to do with the electrical parts of the 4wd, i think the actual problem is in the transfer case motor itself. when i turn my blazer on and start off in 2hi ill press 4hi and itll go into is fine. but as i have noticed when i go back to 2hi the motor clicks 3 times under the car then stays in 4hi, same with 4lo but only sometimes. if you think it is the motor itself then please tell me where i can get a new one for a fairly decent price.
