Door Lock relay
 

Need some help please - I have a 2004 Blazer - I am original owner and am now having problems with opening/locking the doors - one click on the fob opens the driver's door and two clicks on the fob opens the passenger doors, however clicking the rear hatch on the fob won't open the hatch - there is no key access on the hatch so the only way to open it is on the fob - it's a pain not being able to open the hatch - the other part of the problem is that the lock/unlock buttons on the driver's door panel won't work - you can only lock/unlock the doors by using the fob. Any ideas?
