I programed my blazer to my door openers like the manual said and it did take but doesn't seem to send the signal to open the doors on any of the buttons. is this something that I can fix or do I need to replace the opener system.

 

If you followed the manual and it still isn't working, it might be a signal issue.

 

Before replacing the opener system, you could try reprogramming it a few more times or even resetting both the opener and the Blazer. If that doesn't help, checking with a local Portland garage door repair service might give you a clearer idea of whether it's a fixable issue or if a replacement is needed.
