Heater problem
1998 Oldsmobile Bravada All Wheel Drive Automatic

My heater stopped working and only blows out hot air even when it is turned off. My a/c also now doesnt work. Any ideas as to why or the problem?

I assume you meant the A/C stopped working. Has anyone recently disconnected or killed the battery?

No not that I know of. The heater also does not work correctly. It basiclly blows hot air for 30 sec. Then cold air 30 sec. And so on. There is a relay switch that I found below the glove box that I changed because it was making a ticking noise but did not solve the problem. When I unplugged it then it affected the back lights on the truck. So it continues to tick like a blinker is left on. This all happened at once so I dont know if it is related in any way? Thanks

I would try pinching off one of your heater hoses so you can determine if it's a problem with the gas system or in the air controls inside.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
