Removing Guage Cluster

i just got through doing this for the wifes 71 dart. it has the long sweeping type (left to right) speedo set up. it is a pain to say the least to get it out. i have the cuts to prove it! it sounds like you have the same problem with yours i had as well. it only had the speedo and the amp gauge working with the oil light . here is what you need to do to get it out.....the bulb scockets all need to come out. the amp wires can stay connected until you can turn it down and out some then they need to be unhooked as well. there is 2 connectors on the back for the 2 circuit boards. they need to be disconnected before the dash it taken out as well. column will need to be dropped. windsheild wiper switch and headlight switch are not really in the way but it does help a little to remove them as well. you will have to tilt the top of the cluster towards you. be careful when takeing it out . lay a soft cloth on top of the colmn as to not scratch the cluster on the cloumn. once it is out take the bottom of the dash that it sits on and pull it forward some as to open it up some. this will make it alot easier going back in. your problem as to why the temp gauge and the fuel gauge is not working is most likely the metal voltage regualtor on the back of the left side. if this has failed the lights will work for the gauges but the gauges are dead. sadly they are almost always toast as well. when the regulator fails it sends full voltage to the gauges and burns them up by pegging them. i had to send mine off to get mine fixed and got them recalibrated as well. i sent mine to auto instruments. http://autoinstruments.com/index.html. cost with shipping for the repair was 125.00. the regulator is about 55.00 itself. the one they use is a solid state kind that if it fails it just shuts down and dosent destroy the gauges. i was lucky as i had a backup set i just sent them in with my instrument panel. so in a nut shell it is a frustrating job but if you are like me i can't stand not to have at least the gas gauge working. also while the dash is out replace the bulbs (168) with 194's. it will be alot brighter!
