Select the year of your Chevrolet Blazer:
If you’ve got a classic 73-87 Chevy or GMC truck, you know the struggle of staying cool in the summer or keeping the frost off your windshield in the winter. That’s where the Brothers A/C, Heat & Defrost System comes in. This kit is a game changer for your ride, designed specifically for those vintage models.
Installation is pretty straightforward. You won’t need to break out the fabrication tools or make any crazy modifications. It mounts right to the existing holes in your dash and firewall, which means you can get back to cruising without a huge headache. The kit comes packed with everything you need: an evaporator, compressor, drier, all the necessary mounting brackets, and hardware. Plus, you get louvers, duct hose, pre-formed aluminum lines, a hi/lo safety switch, and a wiring harness. Oh, and let’s not forget the new backlit 3-lever control panel that gives your interior a nice touch.
Now, let’s talk specifics. This system is compatible with a range of models, including:
- Chevrolet Blazer (1973-1974)
- Chevrolet C/K 10 (1973-1980)
- Chevrolet C/K 20 (1973-1980)
