I’ve been having this weird issue with my ‘94 Bronco where the heater only seems to blow hot air when I’m accelerating. As soon as I let off the gas or come to a stop, the air goes cold. It’s driving me nuts, especially with winter around the corner. Has anyone else experienced this? I’ve heard a few things like vacuum leaks or maybe something with the coolant, but I’m not sure where to start. Could it be a problem with the thermostat, or maybe the heater core? Any ideas on what I should check first? Would love some advice from someone who’s dealt with this before!
