Have hazard lights but no running or turn signals

What fuse are you pulling ?

Hazard Lamps
The hazard warning switch is part of the turn signal switch. The turn signal switch receives battery voltage at all times through the HAZARD SWITCH Fuse. When the hazard switch is placed in the HAZARD position, battery voltage is applied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher sends a turn signal flasher signal to the turn signal switch. The turn signal switch provides all of the turn lamps and turn indicators with the turn signal flasher signal, simultaneously flashing them on and off.

Turn Signal Lamps
The front turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL Fuse. Battery voltage is then applied through the turn signal fuse circuit to the turn signal switch. When the turn signal switch is placed in the LH or RH position, voltage is supplied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the BCM. The turn lamps are permanently grounded.

Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column - Tilt.

check both fuse boxes,, One is under the dash inside the van, the other is under the hood,,

check for a feed first to teh indicators and the hazard switch if you have a feed then renew the hazard light switch first as this switch if defective will stop all the indicator lights from working

it needs a new hazard switch it run the turn signals to

hi have you tried replacing the relay in the fuse box? does the hazard lights work? do they flash when the button is pressed? if not it is a possibility that the relay is u/s...hope this helps

the turn signal awitch goes bad on those vehicles causing niether to work

Hazard light switch... They all intermingle in operation.
My ex wifes 96TC was doing the same thing... I could OCCASIONALLY get the hazards to work by turning the hazard switch on/off like 10 times in a row and suddenly it would fix... finally bought a new switch

The problem is most likely the turn signal switch located in the steering column, tough to replace without the proper experience and specialized tools. The air bag and steering wheel need to be removed to replace the switch.

Start by checking the fuses. The parking & headlamps work off the same switch. The back-up lamps are on a different switch,which is activated at the transmission.

Did all these problems happen all at one time?? If so you may have a bad body ground. Try running a electrical wire from the (-) negative side of the battery to the body and see if this works. Be sure this wire is to a place with no paint as low voltage electricity will not flow through paint.
A). If not try replacing the turn signal flasher for the turn signal problem. This is usually the culprit and it's easiest and cheapest to replace. The turn signal flasher will be found under the driver side dash next to the hazard flasher. Turn the hazard flasher one to locate it. If you want try swapping the turn signal flasher with the hazard flasher to see if this fixes it. They are the same style flasher.
If this doesn't work you may a faulty turn signal switch or some wiring issues.
B). It could as simple as the head lights bulbs need to be replaced, it's rare but I have seen when both bulbs blew at or near the same time. If your able check the voltage at the head sockets.
C). Could be a bad blower motor or switch. I'm not sure if these models have a resistor block or not. The resister block controls the electrical current going to blower motor which controls the speed of the blower fan.
