Question about 1997 Chevrolet Blazer
Posted by Anonymous on
Maybe true, but your first priority should be to get that ignition switch looked at (three parts - key module, the cable from it to the electrical switch, and the electrical switch, and it's usually the electrical switch), then see what problems go away. If the compressor clutch won't engage (electrical problem), that could be related to your ignition switch problem.

Check both O2 sensor(s) and catalytic coverter.. P0420 means catalyst below threshold. Also check the sensor at the transmission and solenoid.

Your going to have to get the ECM scanned, Auto Zone scan's for free and most garage now will scan for $10.00 to $15.00 since they all have the scanners now and need the business.
You could have a Vehicle Velocity Sensor (V V S) going bad or the wire harness it self. The V.V.S tells the ECM how fast the drive shaft is rotating and calculate's what gear it should be in relative with the engine speed and throttle position, and transmission fluid pressure.
Regardless you need the Blazer scanned to pin point why your transmission is shifting the way it is. Could be as simple as time for transmission oil and filter change for $125.00 or a loose wire harness.
Check your transmission fluid and try not to run the blazer to hard, to replace the transmission start at $1,900.00 for a rebuilt.
Good luck and hope this helps. Keep me posted

Sounds like you have a bad shift solenoid. Not sure if the Chevys are a solenoid pack, or seperate, but it will need to be replaced.

you have a valve body problem, some of the speed sonsor controls are malfunctioning... need to get into the valve body... check fluid condition for dirty and burned condition...
