One of my turn signals wont work, both my headlights only work on highbeams

Replace the turn signal switch. All the exterior lights except the high mount brake light run thru it.

I show the dimmer switch for the headlights being part of the turn signal switch in the column.
What switch on the dash are you talking about ?

Well the turn signals are a different circuit.
Usually the common problem with one headlight is the ground circuit.
Both the high and low beam use the same ground. I would check for power for each circuit and a good ground at the light socket.

look in plug bad or loose connection can cause this problem . check wiring going to other light

you might just have two bad low beam headlights, I have seen it before. Only other problem would be the switch that turns on the headlights is bad. Best way is to Test power going into the headlight when the low beams are turned on to rule out the switch.

My first guess would be the combination/multifunction switch on the column (turn signal arm). Controls all of your problem areas.

Sounds like your switch is bad (i.e. turn signal / healight dimmer / winshield lever switch) inside the steering column. Replace as necessary.

check the headlight relays under the hood also fuses under the hood and in the interior fuse pannel.

check your fuses. hope this help

First off, do you have a knob on the dash for the headlights, or do you have a lever on the column that turns them on? If you have the lever on the column, and you can turn on the highbeams by pulling back on the turn signal stalk, and hitting the hazard button turns the flashers on, then chances are the stalk is bad (it's called the combination switch and it's a common failure on the B5 chassis cars (the Passat and Audi A4)).

Try that out - hit the hazard button and see if the hazards work. Pull back on the stalk and see if the high beams come on (they should - toggling like that uses a circuit that is separate from the usual headlight circuits).

Post back up with the results of these checks:

Headlight switch on column or dash?
Highbeams turn on when turn signal stalk is pulled back?
Hazard button activates hazard lights?

Let me know what you find out and I'll be able to tell you more definitely.
