So im considering a change from my 2wd TBSS to an AWD. My decision to trade up begins with the agonizing electrical issues ive had with my 2006 TBSS. Everything from A/C problems to lock/window switches ect...Ive seen the AWDs prove themselves in the snow but Ive also heard the risk of transfer case fails becoming common on AWDs. So is an AWD any less reliable...help me out????
