Default switching gear problem

iight when I switch from r to d or d to r my car cuts off all the time, it use to do this sometimes but now it does it all the time. any suggestions on what might cause this? Also I looked everywhere and i wanted to know how the hell do you change your heating/ac blower. mine only blow from the front window (defrost) how would you change it to blow air at the foot area or mid area etc...

Since no one has responded to your question, I thought I would bump you back up to the "front row" again. I guess what everyone will ask you is for More Info. Is the Check Engine light been flashing? Have you tried to pull any codes. Have you done anything to modify this car in any way recently? Have you replaced anything? Did you send your mother a Mother'* Day Card? Sorry, Your Witness.

I'm not certain on your shifting gears problem. Any other issues with it? Low idle speed, missing, check engine light, etc.?

As for only blowing defrost, check the vacuum fitting that leads into the firewall just to the left of the master cylinder. It'* sort of tucked under things, is easy to knock loose, and also easy to overlook when your checking for vacuum leaks. If that comes loose, it defaults to defrost mode.

You may have a failing Torque Converter or a bad EGR valve causing your stalling during shifts.
