1999 Chevy Blazer 6 cyl Two Wheel Drive Automatic 136000 miles
This started when I replaced the battery. The A/C worked before new battery installed. Afterwards, the A/C worked however extremely hot air was coming through the vents no matter what temperature setting was. Also really bad smell was coming in as well - smelled like antifreeze. Checked all fuses and they were fine. Coolant levels fine. My mechanic had to clamp off recycling hose to prevent heat from coming through vents. My mechanic checked out motor that controlled the vents and replaced the actuator which got the vents working again, but could still smell odor. My heating coil is not broken - no dripping onto floor boards or spraying of windshield. No leak in the radiator either -- water level and antifreeze are fine. Weird part is that odor comes through whether I have the defrost on, or just using outside air, cold setting or hot setting. Smell is stronger when the Defrost is on and temperature setting is on 78-82. Smell not as strong when temperature setting on 65 and using outside air. My compressor is leaking but by now all of my coolant is gone. Concerned that odor not going away and the more I use the heat the worse it gets.
have the same problem?
