Electrical wiring expert ?

[timbach]

Can anyone recommend a good wiring expert ?
Have problem with my A/C. Sometimes turning on headlamps would turn my compresser off (a/c light still on but gradually air con becomes warm)
BUT turning my foglamps (front and rear) , on and off again , will turn the compresser back on and the a/c will start to get cold again.
Weird but there it is.
Thanks
