Help! My 94 Buick Lesabre started having an issue with the A/C and heat. sometimes the buttons on the heater will not work. if you push the button it stays stuck on whatever setting it is on. we have had a diagnostic computer check that is showing an electric issue but not what specifically is having a problem. anyone ever heard of this?

also, the car is choking a little. someone said it's probably the catalitic converter. what do you think?

Check you fuel pressure. Typically, as the pump ages, the pressure drops, causing the computer to add fuel to the mixtures to compensate. Ray.

I have also had a problem with my 1994 custom climate control unit. On occasion, the unit will just go off, then about a minute later, it resets to defrost. This is most annoying on hot summer days!!! I've only had the car for 5 months, but its only got 116,500km (bout 72mi). The cars hardly broken in!!!

anyone who could help, i'd appreciate it.
