Only blows hot air
New to the forum but hope you all can help, I have a 1998 chevy blazer 4x4. My water pump went out so I replaced it but after that all that blows out of the any of the vents is hot air. The air will blow from all of the setting, ex. vent, floor, defrost, etc.. As anyone else had this issue or know of a fix. Thanks for all of your help.
