Where exactly is the in line fuse for the heater blower located on a 99 chevy express 3500 van with 5.7 350?

Just to add to the previous post. The blower motor resistor is under the hood on the passenger side behind the battery.

Hi,

When you said that you checked the brake switch, did you check it live? Meaning verified live power to the switch, press switch, and then power came out the other terminal?

If so, also verify zero power on brake press, at the offending brake light bulb terminal. You must verify the test light each time you move it...leave running lights on...

After verifying that there is no power coming, after the brake is pressed, note the wire color and find it where it comes to the steering column and test there... This would eliminate wires and connections between front and the rear of the vehicle, unlikely, but needs to be tested.

After verifying no power at that terminal, then yes the t/s switch is certainly suspece. This may be the time to get a mechanic to verify and replace the switch, there are locks, tilt mechanisms, air bags, column bearings, etc involved. Failures risk loss of vehicle control (locking or binding for example.)..

Hope this gets you going in the right direction.

Testimonial: "Thank You. I tried those things and it seemed to be the Emergency Flasher switch in the multi function switch."
