Suddenly Temp gauge stopped working and the cooling fans not stopping..I read somewhere here about changing the sensor & thermostat both together..done the job + changing coolant (all OEM) from GM dealer..started and the same problem still..removed the negative for awhile and returned back..the temp gauge worked but no fans and even with air conditioner not worked!! There is a pressure in the hoses (hard hot when I press them by hand) I heard ( I think the AC clutch) but no cold air no cooling fans only the hot air when I change..
No light ( error code) in the dashboard
Any idea??!!
