My 53 plate punto fine then the hazards will flash and the power steering goes heavy the hazards won't stop flashing until I remove the battery lead

stop at an auto parts. they will show you where the power steering oil goes.

you mean turn signal cam replacment
1 disconnect battery 2remove the hub or air bag on steering wheel (center Part of wheel) maybe two screws in the back of steering wheel remove first 3 remove horn button and steering wheel retaining nut then install steering wheel puller 15.99 at autozone. notice the steering wheel angle it only goes back on one way. 4 next shoulb a lock plate there is a retainer ring remove it with a lock plate retainer tool 8.99 use a pair of needle nose to remove ring dont bend out of shape. 5 now you can remove the turn cam two screws on selector and one screw on the hazard light switch then 3 screws on the cam you will need a # 2 and a #1 phillps for these screws. 6 disconnect power cord it probally goes down through column remove the knee plate to see wires by the pedals. 7 thread the new wire harness back down the column with a piece of bailing wire or equalivent. 8 reinstall all in reverse order.

if the hazzards and the a/c are flashing at the same istance then the problem is something to do with the wiring, they may have put a wrong relay in or crossed over some wires.

It's part of the hazard switch. have to take trim panel off to replace it .Apply the parking brake.
If the vehicle is equipped with a column shift, position the transaxle shift control indicator to 1.
Adjust the steering wheel for access.
Using a small, flat-bladed tool, gently remove the bezel from the ignition lock cylinder.
For the Impala, remove the right and the left access covers from the instrument panel (IP) fuse block.
For the Monte Carlo, remove the left access cover from the IP fuse block.
Remove the steering column filler. Refer to Steering Column Opening Filler Replacement .
For the Monte Carlo, open the instrument panel compartment door.
Remove the trim plate screws from the IP cluster.
Start at the left side of the IP cluster trim plate. Grasp the trim plate and carefully pull rearward. Disengage the IP cluster trim plate in order to easily access the hazard warning switch
Disconnect the electrical connectors from the hazard warning switch.
Remove the hazard warning switch from the IP cluster trim plate.


It's probably the switch on the steering column ! An not the flasher but you never know without testing .

First, is it doing it on BOTH isdes or just on one side? Example: turn signnals flash OK when turning left, but only come on and stay on when turning right. If it is doing this, then you most likely have either a blown bulb or a bad bulb socket on the side that is not flashing. You need to check both the FRONT and REAR bulbs to make sure they are all functioning properly.
If it is doing it on BOTH sides, then you either have a bad flasher, or at least 2 bulbs burned out (one or more on each side).

Are you sure you replaced the correct flasher? The flasher for the HAZZARD lights is plugged into the convinience center under the left side of the dash. If this is the flasher you replaced, it is the wrong one.
The turn signal flasher is mounted to the driver's knee bolster bar near the steering column. It is held to the bar with a clip. (see diagram)

Maybe one of the key fob's has gone nuts.. remove the battery from them both and see if that stops it.

either pump failure...eg no pressure but no leak or steering rack failure,is power steering belt tight and spinning ok???

Under your dash by steering column,by your left knee, is a small 4" x4" box that has a small wire attached. On the end of the wire is a small button. Push the button with the ignition in the on position. It will reset the alarm system. That will stop your lights from flashing. Have a great day.

check to see if you have power at the hazard light switch, it could just be unplugged, if u can get another good switch swap them over, i know its a power prob to that haz switch.
