2001 PT Cruiser loss of turn signals and hazard lights after multi-function switch replacement. I replaced the multi-function switch after noticing the fogs lights staying on when not engaged. When the new switch and flasher relay were installed, the lights worked correctly however, I could not get the turn signals or the hazard lights to work. After ordering a 2nd multi-function switch and installing it, nothing worked. I have installed the 1st replacement switch again and found that the under hood fuse for the hazard light had blown. Any replacement with a new fuse shorts out immediately. I have looked for frayed wires without any luck. Any suggestions?

There should be 6 relays in the fuse box. Using your manual, find the turn signal relay and replace it.

There are two types of PT Cruisers, those that the multi-function switch (the one on your steering wheel that controls turn signals/foglights) HAS failed and those that it WILL fail. Yours probably has failed and your fog lights come on whenever they feel like it, even if the car is parked with no key in the ignition, thus your need for a new battery. You can find the replacement part on Amazon (Amazon com Shee Mar SM147 Turn Signal Fog Lamp Wiper Dimmer Multifunction... ) or have your mechanic replace it.

Replace the multi- functioning switch. it operates the turn signals,4way flashers,wipers and headlights.those are very common problem

You will need a new multifunction switch, not a fuse. this is a simple repair. Remove the upper cover from the steering wheel and then slide the multiswitch up and off. that's it

On the Multi Function Control Lever (Turn signal Switch lever) there should be a center section that will rotate to control the dash panel light brightness, and dome light.

There are just (3) possible reasons for this:
(a) your headlight switch has failed, or
(b) your headlight relay has failed.
(c) Fuse 1 (25 Amps) has blown

The headlight relay and fuse 1 are located (I think) in a fuse/relay block under the hood.
The headlight switch is part of the "Multi-function Switch" on the steering column.

Here's how to replace the 2001 PT Cruiser multi-function switch:


Multi-Function Switch Removal & Installation
1. Open the hood.
2. Disconnect and isolate the battery negative cable.
3. Remove both upper and lower steering column shrouds.
4. Disconnect both posi-lock harness connectors at the rear of the multi-function switch.
5. Remove multi-function switch mounting screws and remove switch from vehicle.




To Install the new multi-function switch:

Note:
If replacing the multi-function switch, the combination flasher and windshield wiper/washer switch
must be transferred to the new multi-function switch.

1. Remove the two Torx(R) screws retaining the wiper/washer switch, place next to the new
multi-function switch and install two screws.
2. Place switch into place and install mounting screws. Torque multi-function switch to column
retaining screws to 27 inch-lbs. (3 Nm).
3. Connect both posi-lock harness connectors at the rear of the multi-function switch.
4. Install both upper and lower steering column shrouds.
5. Connect the battery negative cable.
6. Close hood.
7. Verify vehicle and system operation.

yes , that sounds like the multi switch... in the column...

Replace the multi-function switch in the steering column. The 3rd brake light is powered directly off the brake switch while the regular brake lights are wired thru the turn signal switch. Common problem

It is a bad multi function switch in the column. I have the same problem I am researching no here is a link to help explain

Good Luck

I have a 2002 and one day had no headlight or dash lights. The tail lights, blinkers and hazards work just fine as do the radio of dome lights. Changed the multi-function and checked all fuses, but no help. I am interested in the solutions as well.
