I have an '87 Ramcharger Royal SE that has developed some electrical issues.

#1. When starting, I have to turn the key to start and jerk the steering wheel to the left to get it to turn over. If I don't jerk the wheel, it does nothing.
#2. My heat/ac blower no longer comes on. The blower still works, just not from the controls ( I wired in a toggle switch so I could at least have heat).
#3. My windows no longer work. They both have brand new motors, which still work when I wire it straight to the battery.

From what research I have done, this is a common problem with '70s and '80s mopars. Has anyone else had this issue, what was the cause, and how did you fix it?

Thanks in advance

 

Not being there is a problem as it's hard to diagnose long distance. However, just guessing here, #1 and possibly #3 sound like a problem with the ignition switch. #2 sounds like your blower motor resistor block. Those eventually melt or fail and may run full blast or not at all.

 

From what research i have done online for #1 and #3, thats what i have read. The problem is either the switch or the main wire connection. As far as the blower, ive read a couple things that say the switch/wire connection could also cause it to go out.

 

I'm pretty sure your blower problem is the resistor block. I don't have a first gen right now and haven't had one for several years. If I remember correctly, the resistor is behind the glove box and mounted on the blower housing. There's a plug on top or the side and it mostly sits inside the plenum so the air blows over it. It's a common failure. Either the fan will only blow on high or it won't blow at all.

 

You need to investigate the ignition issue but i would bet it's the ignition switch. Have seen all the issues with blower, Mainly a bad connection on the resistor or fan switch. Hi fan bypasses the resistor, Each of the slower fan speeds use a different part of the resistor.If the window motors work it has to be in the wiring or the switch/es. Look up the wiring and go from there.
