Check the SI for instructions on using the TECH-2 and SPS to reprogram the HVAC module. Battery replacement should NOT require doing this, however. Replacing the battery will, however, require recalibration of the HVAC doors if you screw it up by completely discontinuing supply of 12V.
Luckily, it's easy to recalibrate because the GM guys know what kind of idiots they have to dea shiat happens. Anyway, disconnect the battery, with the key in your pocket. WEait ten minutes, ne less. Ten reconnect the battery, turn the key to ON (be sure you know what ON means) and wait another two minutes, then shut it off, start the engine, and set the clock, radio, and compass.
There should not be any reprogramming necessary for that unit just drive and the computer will use pre stored maps and functions.
Try replacing the A/C Blower relay

no need to change the copper tube if the capacity of the unit is same.
no, unless u have to remove the compressor unit. The clutch can be replaced with out removing the compressor if you have room to do it.
The best practices for maintaining and replacing the air filter for an AC unit include checking and replacing the filter regularly, typically every 1-3 months, depending on usage. Use the correct size and type of filter recommended by the manufacturer. Make sure to turn off the unit before replacing the filter and follow the manufacturer's instructions for proper installation. A clean filter helps the AC unit run efficiently and improves air quality in your home.
It could be the electrical unit in the car or just that the battery is low that's messing with the ac.

If your AC unit fuse keeps blowing, you should first try replacing the fuse with one of the correct rating. If the fuse continues to blow, it may indicate a more serious issue with the AC unit that requires professional inspection and repair.
Common causes of an AC unit experiencing a hard start include a faulty capacitor, low voltage supply, or a compressor issue. Solutions may involve replacing the capacitor, checking and correcting the voltage supply, or repairing or replacing the compressor.
remove your battery cable for about 5 min or so, then replace it, then turn truck on and turn radio ac heater electric windows...headlights etc..run all elect functions.......computer then will reprogram.....it should work.........
