No Low beam head lights and no turn signals or hazard lights. Already changed the multi function switch. What to look for next?

Does it do the same with the lights on 'High' beam? If it works correctly on 'High' beam it could be the switch in the lever at fault.
Next check the fuses for the turn signals and the Hazard lights. They will be in the fuse box under the hood. Some vehicles will have separate fuses for Left, Right and Hazard lights others may share fuses.
If the fuses are OK it could be a faulty flasher unit. Check to see if the hazard lights work correctly. Some vehicles use separate flasher units for turns and hazards and others share 1.

Doesn't have a turn signal flasher , use's lighting control module .
Turn Signal and Hazard Lamps The turn signal system consists of:

• turn signal miniature bulbs (13465).
• turn signal indicators in the instrument cluster (10849).
• lighting control module.
• multi-function switch (13K359).
• circuit wiring and circuit protection.

Power is supplied to the lighting control module through instrument panel Fuse 6 (10A). This fuse is hot in START or RUN. The lighting control module is connected to the turn signal switch portion of the multi-function switch. Ground is provided to the lighting control module and the turn signal miniature bulbs through Circuit 57 (BK).
Turn signal functions are performed by double filament bulbs in lamp assemblies located next to the headlamps. The turn/hazard function uses the second filament of the appropriate bulb(s).

• With the multi-function switch in the right turn position, power is supplied to the RH front and rear turn signal miniature bulbs and the right turn indicator in the instrument cluster.
• With the multi-function switch in the left turn position, power is supplied to the LH front and rear turn signal miniature bulbs and the left turn indicator in the instrument cluster.

Check your fuses first and then check your hazard flasher relay. As for your high/low beams, could be your head light switch itself.

could be a fuse or the relay or simpler the elements in the lights blown, yes even both of them.

seems like the multi-function switch is failing
easy to replace and fairly common

a faulty multi function switch...the milti function switch is the lever u pull to go from low to high...an to turn on the lights

I suspect a bad multi function switch located in the left hand side of the steering column. This switch controls your high/low beams/wiper delay/windshield washer/turn signals and hazards.

sounds like the problem is the dimmer switch, get a price on the dimmer switch. If you have to, get one at a junk yard . It's cheaper.

Either the low beam head light bulbs have went out,or the dimmer switch has gone out.

Remove the plastic trim from around steering column so you can access the wires to the multi-function switch(turn signal switch).The RD/YE wire is the feed from the headlamp switch for low beams,it then leaves the multi-function switch on the RD/BK wire and feeds fuses no. 10 and 4 in the under dash fuse panel and from there to the headlamps right side is the DB/LG and left side is the WH/LG. Get you a 12V test light and make sure you have voltage in these places. I suspect that the multi-function switch itself has gone bad since you stated that they would work at times when you activated the turn signals.
