1987 blazer power door locks help!

I have a problem with my power door locks. I changed both door poppers and switches and this is what the problem is. I can lock both doors with the passenger side switch, but cannot unlock. On the drivers side it doesnt lock or unlock. It is starting to be really aggravating! If any suggestions please help.

Check All the plug in's.

With my 85 when I had the drivers door apart I didn't quite get the plug into the switch pluged in all the way, so the doors would both unlock from either side, but wouldn't lock from either side.

I really should pull the panel off and fix that soon :rolleyes:

The drivers door seems to be the master side, so check that side out first

Thanks for the input on the power door locks I will try that one. Are there any relays involved in the door locks?

mine are factory, and I only had to take the system apart enough to take the door off, so I don't know about any relays
