Question about 1989 Chevrolet C1500
The output on the a/c is full cold air, yet it is making a very loud rattling noise that gets worse each day. I can't figure out what is causing this noise. Any help would be appreciated here.
Yes time for a new ac pump it is wore out. Sorry for the bad news but the ac pumps dont cost that much.

one or more of the pulley's is defective, most likely the tensioner pulley, but check them all for wear and side to side movement which indicates a worn bearing, this causes the belt to not run true and chirp.

Watch out! You might have a loose wheel! Check those wheel nuts. If not, a loose brake caliper, or last if not least, a bad wheel bearing. Don't drive it until you find out what the heck is wrong! Could be dangerous.

Had the same thing happen to my truck, the blen door actuator is under the console on passenger side, but the heater core is going to be clogged if you dont have any heat coming through, but a/c works..

Feel the hoses going into the heater on the firewall. If one is hot and the other is cool, then the heater control valve is not working for whatever reason. Check the flow valve.
