Everything else work's besides my temp guage and my oil pressure guage? Ive checked and double checked the wires and connect's and they are all good but no cigar!

Today i went to the local junkyard and picked up another coolant temp sender and oil pressure sender,installed them started the car and still nothing out of ethier of them?

Im kinda stumped? all my fuses are in good shape the only thing i could think it could be is the plug going to the bak of the guage cluster but how would that get loose?


Any idea's guy's? Car is an 84 gs-l.

 

Check the large and small connectors @ passenger side firewall.

 

Ok i will check them they do look very corroded.

 

I disconected the two electrical plug's the small one and the large one. They were very corroded by dirt i cleaned em up and clicked them back together and started the car but the guages still dont work.

Does this mean that the plug going into the back of the guage cluster is loose/disconnected? Or if its disconected would all the guages not work?

Any more idea's?

 

Bump

I dont want to tear the guage cluster out
