Issue / Question:
Hello and thanks in advance! I have a 1999 Chevy Blazer that is in near perfect condition! I love this truck. When I was buying it, I noticed the A/C blew only ice cold air and had no temp adjustment. Told the folks at Holler if they fixed it I’d buy it. They spent near 1000$ in replacing the heater coils which they said were clogged, etc and it worked fine for awhile. So I bought it. Now 5 months later after the cold snap is over I went to use the A/C and I get no A/C just warm air. Freon R134 is perfectly charged per gauge, no leaks, compressor works, evaporator gets cold. Replaced the switches in dash, 500$new/ bought used one for 40$ from wrecker yard from well maintained vehicle, still no A/C! All fuses checked, vacuum lines behind glove box attached and move appropriate, idle not rough. I don’t seem to hear that big whoosh as it transitions from heat to A/C and heat won’t get Hot. Like a baffle is stuck or something. In a quandary. Definitely need it fixed. Seriously limited budget. Friend from Road Rangers highly recommended your advice as well as services. Advice and a fix would be appreciated, willing to bring it in for estimate. Willing to talk on air if you all wish!

Sounds like a blend door motor problem, we can use the Tech 2 scan system and see if the blend door is moving or not, we will need to start there. Let us know 407-629-2661.
