    I have the same problem with my 2000 Jetta - the hazard light switch was subject to a recall, I had it switched by the dealer. Very shortly that switch failed so I bought another one, this one was bad out of the box and makes a noise like you describe. It's definitely the switch, because the type of noise will change when you change the switch from one to another. One makes a random clicking noise and the other a "staticky" noise like a gieger counter. To have 3 of these fail is incredibly bad, so I plan to discuss it with the dealer. I will let you know what they say.

SOURCE: how to replace a coolant temp sensor on a 2001 vw jetta 2.0

Yes it is that easy. It should be a 4 pin connector located on the transmission side of the engine head in a plastic flange. Best is to wait for the engine to be cold. Unscew the radiator cap to relieve pressure but screw it right back on. On the 2.0L engines when you unclip the coolant sensor little or not coolant loss will happen if you do this. Just unplug it, pull out the clip, pull out the sensor, and the seal which sometimes stays stuck. Install the new sensor with a new seal lubricated with some coolant, make sure it's well seated and reinstall the clip. The sensor is well seated if the clip fits right over the top, just make sure both sides clipped into position. Replug it fill the coolant with VW original coolant mixed 50-50 with water if needed and done. If you have a fault you might need a scanner to erase the check engine or fault in the cluster.

What's the reason for changing it? Eratic temperature readings?

hi from uk from the symptom/location you say water leak is coming from ? this is most likely to be the water pump that is leaking ? considering age/milage ? this is not uncommon however as the water pump is driven by cambelt this unfortunately means you will have to replace the cambelt and tensioner as well as the water pump it is policy never to use old belt/tensioner once disturbed for obvious reasons i'm sure you have heard stories of result of cambelt failure? and the serious damage caused to engine ? also if leak is serious? this will deteriate c/belt so advice you consider renewal asap cambeltkit +tensioner in uk casts approx under £45 and w/pump a little less you can obtain from most good motor factors/superstores avoid dealers this job is not too difficult diy with haynes or w/shop manual if you follow instructions and have tool kit hope this helps?

Where is the hazard light switch ?

it usually depends on what you are driving some are on the dash some are in the middle of the dash around the radio some are on the searing column. what you are looking for is usually a red button with a triangle on it.

Where on dashboard is hazard switch

The Hazard light switch is located in the middle of the center dash vent. The vent in the middle of the dash has two adjustable vents and the button that turns on the hazard lights is in between the two vents.

My brake lights work intermitantly with jiggling the hazard switch on the steering column

The hazard switch is problematic on many GM vehicles. Find an aftermarket replacement, and change it out. The solder joints on them would crack with exposure to cold and heat differentials.

Seems your flasher is going out. If i am correct the switch for your hazard lights is also your flasher. One way to find out is when it stops working tap the hazard light switch and see if it starts to work again. If so there is your problem. Hope this helps

Clicking in dash sounds like turn signal relay. We think it may be hazard switch malfunction anyone know ?

we have an 03 grand am and took to mechanic. he replaced relay behind dash in center area behind radio. it still made clicking noise and he said it needed a new 250.00 plus turnsignal switch. went to junkyard and got one for 14.00. but it didnt help

we disconnected battery ( hoping that would eliminate chance of air bag going off) took out turn signal switch. placed switch on bench and took it apart with a T-10 torx bit. and cleaned TURN signal contact points with cloth. regreased a little with some of the grease that was in there. (not sure what kind of grease it is) Put back together and it seemed to eliminate clicking noise.

2003 pontica grand am making clicking noise

The turn signal flasher and the hazard flasher are both integrated in to the hazard warning switch on the dash,this is acually called a Hazard Warning module,there is a GM bulliten for this,it is acually a recall for the complaint your having, the GM bulliten # is 03043A and the dealership will replace the Hazard Warning switch module at no charge to you,GM knows about the failing switch and that is why they issued the recall on them,so i suggest you bring that car into the dealership so they can replace it at no charge parts and labor,bring the campaign number that i gave you that way theres no guesswork.oh and it only takes about 10 min to replace :).
The clicking noise is the faulty flasher relay module, it's been know that the flashers are still funtional and you can hear them working but don't have enough voltage to activate the lights. I could be wrong. LOL Good luck and hope this helps.

Try replacing the Flasher first before spending to much money for a possible simple fix. If it's not your flasher then it could be the turn signal leaver.
Ok, this may seem stupid, but that's what they did to the blazer. They set the flasher near the middle and under the center console behind the radio.

It's to the left of the radio right behind the dash. The hazard flasher and the turn signal flasher are side by side.  It right next to the Cig lighter behind the panel. They do mark the turn signal from the hazard flasher on the plastic behind them. Turn is on the right.

Good luck and hope this helps.
