Heat/AC controller on 1992 chevy pickup quit working after changing batteries

SOURCE: Heater controls just quit working

I have a 92 Suburban with the same issue (been going on for about a year) AC will turn on when hit a bump in the road... and off with the same type of bump...

I had researched just about everything including replacing the RELAY behind the glove box...

this still didn't help...

finally after replacing most the hardware... I started tracing the wires and found that there is a plug under the glove box there there is a HOT (red) wire that was overheating due to a bad connection and it was melting...

here is where my plug is...
- open the glove box & remove the door
- remove the screws on sides of glove box and remove the glove box it's self...
(you should now see many wires and things)
- now this is where I replaced the relay... I think it was the middle one... if you replace it you will want to refer to a manual or call a dealership to make sure you replace the right one... (it was like $24 or $27)... here is a link to what the relay looks like...
-then if you follow the RED wire out of that relay.... about 3 feet of wire or so.... you will find a connector... with 5 Wires (Mine are colored - Red, Orange, Lime, Black and Green)

** this is the connector that seems to be my problem

Either Replace the Connectors or the (cheap way to fix it is remove the connector and clamp and/or sodier each of the 5 pairs of wires together without the plug... )

I am currently waiting for a new plug from my local dealer but I have bypassed the connector and manually connected the wires until the dealer gets the connector get it...

Hopefully that helps...
