Check Engine - P0500 Code - Speedo OK, No Cruise Control

Hello,

My 98 LSC has been spitting out P0500 codes, and my cruise control has stopped working.

My speedometer & odometer work fine, but the cruise control does not. I have had the VSS replaced by my mechanic, but the problem persists. I have also gone through the cruise control diagnostics (key on while cruise "Off" button pressed, etc.), and get no errors from that.

On a possibly related note - the problem surfaced right after I replaced my heater blend door (second time - this time with the slotted link arm), so it seemed too much of a coincidence, and I figured I did something to cause the problem. But I can't figure out what that might be.

Any help would be greatly appreciated.

Michael
