Hi I am having some issue's with a 1968 Newport first off I have no right rear signal light or brake bulb was replaced front works fine and passenger side is fine ???
next my fuel gauge sending unit wire has no power and my blower motor does not come on couldn't find any fuses ?? can someone help me please

 

Check for hots and grounds for the bulb issue
Sounds like you have a broken wire someplace between the sending unit and the dash gauge.
So you have checked and have not power to the switch or the resister for the blower. Check those.

 

Where do you check for power for the blower motor ?

 

Start at the blower motor and work your way back.. Follow the wire if you dont have a wiring diagram..

 

No power at the stud on the fuel gauge and I think the blower motor is shot wiring looks okay. how hard is it to replace the blower motor on this car ?

 

So you checked and you got power to the Blower Motor wire?
Should net be to hard to replace. Is that blower behind the glove box or out under the hood next to the passenger side fender... I don't remember at the moment...

 

The weirdest thing is the right rear has no signal or brake light working ? The front signals work fine ? replaced the right rear bulb already ?

 

Do you have hot wires at the lights? If so it's the bulb socket not giving the bulb power or no ground.

 

Does anyone have a wiring diagram for the tail lights ? I have no power on the one wire for the right side brake light and signal light on the rear
gas gauge terminal on back has no power on it ?

 

The tail turn stop is one your going to have to follow, the maybe a plug on it at about the wheel house but they will go to the front probably under the silplates in the door openings.
