Hey I believe my drain hose is clogged because my passenger carpet is getting wet it doesn’t smell like coolant and I’m not losing any coolant and only does it when running the a/c. Is there a easier way to unclog it without having to remove the passenger tire and inner fender?

 

I don't know about Blazers, but I think people have used a flexible yet stiff rod to try to unplug such tubes on other vehicles. If it is roughly a straight run of tube, you might try using some wire but I think I'd try using some stiff monofilament line such as for a weed-wacker first that has its end rounded by a flame so to minimize the chance of puncturing the tubing.
