The blinking lights in the rear wiper rear defrost area can be reset by holding 2 buttons of the 3 on the left hand side. The top and bottom buttons. Turn the key on and hold them for about 10 sec and they should start flashing differently. Just let it do this. After they start flashing different. It will take 5 to 10 mins. Then one or more will quit flashing all together. If they don't after about 20 min reset them again it can take about 5 trys sometimes before they all go out. Good Luck

hi, well u don't need looping in salary computation. here is the program:-
#include<iostream.h> #include<conio.h> int main() { float bs,gs,hra,da; cout<<"enter basic salary"; cin>>bs; hra=40*bs/100; da=20*bs/100; gs=bs+hra+da; cout<<gs; return 0; }
regards, poly

im assuming you dont have the old one. typically it will be 20-50a. i recomend consulting the manufactures website.

Your Climate control unit may have to be reset. The reset works as follows: With the key in the ignition and in posistion 2 push both the defrost button and the recirc button (at the same time) for five seconds or untill the led lights in those buttons begin to flash. Wait for 30 seconds or untill the led's stop flashing. Switch off the ignition. Check the evaporator temp sensor and pressure sensor for correct functionality.

Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.

The Amp and the Car head unit should be on a separate wire. The Amp should run directly to the battery and be at least a 8 to 12 guage wire. If it is not, you will get this type of symptom. Good Luck Please dont forget to rate this thread
