My blinkers aren't working at all. Is there a fuse that is burnt or is it something else?

You obviously have a bad connection somewhere in the taillight. Some trucks it is a common problem and the taillight circuit board is the problem.

Sounds like you have shorted something out. When you add or remove something you should always take one of the cables off the battery. This prevents a lot of problems later.
Hope you did not burn one of the wires apart. and check all the fuses. If the wire is burnt you should replace it or make sure to tape it real good if its just the insulation that is burnt off.

have you started by checking your fuses?

Hi, I would check the flasher unit as well as fuses 3 and 16. The flasher may be in the fuse box. If not, check under the dash.

Cabin air filter is plugged. Replace and vacuum out housing. The smell is coming from the fan which is being over worked.
I am not a mechanic but use my technical training to save on expensive repairs.

pull each fuse one at a time and check to see if the wire is burnt in two

That would most likely be the switch itself. Fairly common

Check all fuses. Use a test light to check if there is current to the rear bulbs when flashers engaged. If there is, then replace the burnt bulbs. Check for ground at the rear lights.
Do the front marker lights work when engaged??

yes you have a short somewhere have you recently had any aftermarket stereo equipment installed? If so that is where your problem is

Using a test light check to see if there is power to the wire at the plug where the bulb is for the blinker. if so the socket is bad. if not check to see if the light assembly is working for ex. the parking lights or the brake light ect If those lights dont work then check the fuse for the right rear tail light. Hope this helps.
