Hello all,
I have a 71 coupe with A/C and I am currently trying to figure out why the blower motor is not turning on. It has worked in the past, then it the lower settings stopped working, then all together. The switch itself is a little hard to push up, but it gets there with a little force. I thought I would focus on the switch first as it is easier to get to than the actual fan motor and because of the stickiness of the lever.
I was inspired by this site, and with a great write up I found here, I tackled taking apart the center dash in the last couple of days.
There seems to be some discoloration on the top post of the switch and it was a little wiggly. Also on the plug it looks like some gunk on the corresponding opening. Maybe there was a short and that is melted plastic?
Also I found a plug on that same harness piece, back on bottom -drivers side, but I haven't a clue what it goes into. I thought this might have been a case of something becoming disconnected and tearing it apart would reveal the culprit, but no dice.
Any thoughts? Also is there a good way to check the switch and plug? I know to check ohms, but what two parts should I be having the leads on?
I missed checking the fuses, (that should have been first, but I was all fired up about taking things apart.) but I'll do that tomorrow.
Thanks!
