I PUT IN A NEW WIRING HARNESS IN MY 97 BUICK LESABRE AND PUT THE OEM RADIO BACK IN AND WHEN I TRY TO TURN IT ON THE LIGHT ON TEMP CONTROL BLINKS I DON'T KNOW WHAT'S WRONG I MATCHED UP THE COLORS FROM THE HARNESS AND THE WIRES THAT WAS IN THE CAR BUT SOME OF THE WIRES ARE THE SAME COLOR WHAT SHOLD I DO

Please don't use caps when posting here. It's hard to read and considered shouting. (But then again, as a GM owner, one has reasons to shout) SMILE
It seems that there is a wiring/sensor issue to look at here. The temp sensor is connected to the cooling system on the engine block. This sends a voltage value to the ECM, (Engine Control Module) and then to your dash display. If the voltage values are out of calibration, (Normal operational ranges) this will set a code in the ECM and the dash lamp will come on. GM cars use data bus lines through the radio and if we put a wire in the wrong place, expect trouble.
If there are several of the same color wires in the harness, you'll need to count the pins and match each wire to the correct pin connects in the harness. If a single pin gets the wrong signals it needs, this will create the problem mentioned and possible others you have yet to discover. The pins and sockets each have a specific function. Get them mis-wired, expect problems.

PS I am not an expert on GM cars, but after owning, driving and fixing them for a few years, they are quirky to say the least. I finally bought a GM garage manual for problems I was having with a 1990 Olds Trofeo'. It took me 2 weeks of reading that section of the manual to test the possible issues and figure out the codes. After considerable testing a few phone calls, I was able to determine the problem component and replaced it at great savings compared to the dealer cost.
PSS This car was in the dealerships garage for 4 days and they could not fix the problem. That blew $300.00 w/ no corrective results. That's when I bought the shop manual they use and found the the root cause. In a nutshell, if you plan to keep this car for more than 2 years, consider buying the GM manual. It saved me lots of guessing and major $$$'s on other issues that came up later.

i would suggest pulling out the radio and start clipping wires one at a time until it goes away. when it does, that wire is the culprit.
are all your speakers working, and does the radio turn on and off with the key while retaining memory??
