Hello All,
The windows on my 99 Suburban are not going down when I try to open them with the master control switch. My first assumption is to replace the master control switch. But I want to make sure it is not anything else first.
Symptoms:

Windows sometimes do not go up or down with master control switch
Windows will not go up or down when tried with switch at window
Happens more when it has been very hot.

If the master switch is faulty, will the other window switches also fail to work?

Any suggestions will be greatly appreciated. Its a pita when you cannot put down the windows when its 99 degrees outside.....

A
