my abs idiot light comes on in my truck,what things can I check to see what's causing my light to come on? I checked the brakes and they seem okay added some brake fluid because the fluid was low.
Heater will not blow warm air, Ac will work. I’ve changed the water pump, thermostat, heat control switch, ensured the vent is switched to heat. both hoses are hot coming off of pump. Truck is running at correct temp. any ideas of what else to try?
