04 bobcat 331g??

Just picked up a bobcat 331g. 04 with 2000 hrs. Is there anything in particular to look for with this machine? It's pretty darn clean compared to all others I have been looking at. 1 damp hose, strong,all pins tight,good tracks. Only issues I can find are one minor hose weep, 2 speed switch doesn't work, and blower doesn't switch to heat. A.c. works but won't switch to heat. Any insight?
