Can you please tell me where is the turn signal flasher on a 1986 oldsmobile cutlass supreme brougham

On 1980 and later models, both the turn signal flasher and the hazard flasher are located at the lower left hand and the upper right hand corners of the fuse block respectively. Remove these by pulling them from their connectors. The lower dash panel may have to be removed to gain access to the unit. 26295825-zph2pj5z4kfac3kr23sxzldg-4-0.gif

I have one in my back window it work but my tail lights brake lights do not work on my 86 cutlass

Start with your fuses under the dashboard by the driver's shin bone. Remember that fuses can be burned out and not show it. Take a test light or meter and check the contacts on each end where the fuses go, with the key on, and the lights on, to be sure there is electricity getting to the fuse. After that, check each light bulb in the rear of the car. Remember, the bulb can be burned out and not show. Also check your clearance lights on the rear. Take a test light or instrument and check all the sockets to be certain the electricity is getting to the socket when the lights are on and when the brake pedal is pressed. God bless your efforts.

Why do it take my 1986 cutlass so long to change.

What do you want it to change into? If you are saying the trans doesn't shift into the next gear soon enough, could be vacuum leak, dirty filter in trans, someone put a different governor in trans. Most likely vacuum leak. Use gauge to test while driving.

I have an 1986 olds cutlass supreme. I need to install the rear window molding trim that goes just over the trunk lid (side trim and roof trim are already installed with clips). Do i need special clip

yes you need the correct clips and it's real hard to install the bottom rail if the top and side rails are already on since the sides go over the bottom and the top goes over the sides to keep it from leaking.
