So I’ve been having problems with my turn signal is not working my hazards work, and if I step on my break and hit my turn signal, it’ll blink one time, but it won’t blink on my dash I also believe that my reverse lights are not working my radio acts, very weird and will glitch from one speaker to another and if I turn the volume up really fast it’ll switch to only the right side my heat and AC also do not work and I’ve replaced almost everything to do with every component such as blower motor blower motor resistor my key my ignition switch my turn signal switch relays fuses I don’t know what the problem is and I really just need help.
Problem with turn signals ac and heat and radio
- Thread starter funoof
- Start date
Is this from a car thats never had a radio swapped out or something extra installed and have messed with the wiring under the dash?
It has an aftermarket sound system, and a fully built supercharged motor so it’s had work done engine wise, and there’s a sub in the back but I don’t believe that having an aftermarket radio would cause turn signal issues and reverse light issues or heat and AC issues My heat works great. But the only problem is nothing blows. And I’m hearing the AC system activate when I switched the modes like feet or head but it doesn’t blow

sounds like you have a few different problems there that we will need to probably separate to fix.
Fist step, check all your fuses both under the dash and the hood. Don't bother with the manual it is faster to pull/inspect each one and it is only after we verify that they are all good that we can assume thing should be working.
The turn signal problem is often as simple as the multifunction switch or the harness that goes to it. I would start there with an inspection myself
The radio problem sounds like a problem with the radio itself or maybe the wiring. Pull the deck out and be sure there is not any copper wiring showing anywhere, if it is insulate it with some tape or something.

I’ve done almost all of that and replaced almost all of those all of my fuses are good and all of my switches and relays and everything
I’m thinking it’s a ground problem or something rong with my gem module but I kind of suck at wireing stuff and need some help on a call or anything I jest need help

I am not aware of the lights going through a gem module and I know the radio does not. Grounds are always a great place to start right after all the fuses.
A lot of times previous owners swap out headunits and destroy wiring inside the dash and thats the info i was extracting.

yea the radio is more often the not the wiring that someone hacked up either in the dash or under the rear package tray if they do not understand the mach system. The radio should have nothing to do with the turn signals or the heat/ac blower other than something might not be hooked up behind the dash for it.

there is a really good chance the old stock vac lines going to the back of the controller need to be replaced.
All good information!
