97 Catera, Several Problems, Please help!

[Tripseleven]

Hi, new owner of a 97 Catera with 90K. Several Problems, please help!

1. No AC or Heat, the display works but nothing happens when I turn on the fan. Any one know what this is and how to fix? Body Control Module?

2. Service Engine soon light is on, engine has a "miss". I have been told that its a fuel injector, how do I know for sure?

3. Passenger door is stuck in the lock position, I can not open or unlock! This one is frustrating! Anyone have this one out there?


Thanks and any help is appreciated!

1. did the fan go out in stages? or all at once?
check fuses and relays first!
if low and med went, but high fan for A/C-heat was still on; then the resistor module (about $110.)
if all at once, pull and bench the fan motor

2. get the codes read. just guessing is not an option on newer computer controlled vehicles... you could have a "miss" from an engine misfire (which could be an injector, plug, wire), or you could have a miss from a clogged Mass Air Flow sensor, or a vacuum line leak.
Go to AutoZone, get the code read for free, and then post back, and someone can better assist you with diagnosing the problem.

3. when you hit the keyless remote, listen to inside the door...
does it sound like the elec.lock solenoid is hitting, but not unlocking the door? could be merely the mechanism rod has come apart, or something is impeding the travel of the plastic lock knob on the door panel.
if there is no sound, could be a bad lock actuator.

hope this helps,
