I recently bought my grandfather's old Dakota and while driving it one day the radio and HVAC randomly stopped working. I checked the all the fuses, even the under hood fuse, and they are all good. The radio gets power because I can hear the tape player mechanics when I start the truck. Anyone know what my issue could be?

Here is a link to help if you want to try to fix the radio https://www.allpar.com/threads/fixin...ost-1085222574
IDK what the HVAC issue is but if it isn't changing the outlet for the air when you select it there may be a vacuum issue. Oh and there is a blower motor resister. In mine it is on the passenger firewall, a the wire harness plugs into it. Search this site for other info and there is a 95 factory service manual in the FAQ section that may help.

I've got a '96 Dakota 3.9L V6 SLT with the very same issue (no radio display and no HVAC controls working). I can press the buttons to alter the vent outputs and I can hear them switching, so vacuum seems to be fine. My issue appears to be all electrical. Any other things to check and was there a resolution to this issue?

Just as a follow-up, spraying contact cleaner (Caig Dioxit) on the blower motor switch helped and I'm getting at least 3 speeds out of the blower motor now. I also went ahead and vacuumed out the A/C system and checked for leaks. After about an hour of sitting, the gauges still held a steady vacuum state on the A/C system, so I went ahead and charged up the A/C system with 2 lbs of R-134a. The A/C clutch started to engage on & off after getting the 1st can of R134a entered into the system. Everything is now working as it should and it gets ice cold in the single cab truck.

Well I can't explain it and I'm not saying this is actually the fix but this is what happened for me. After changing a lot of ignition components I got an error code saying the front O2 sensor was reading lean. Finally got around to replacing it. When is started the truck back up I noticed the radio was displaying the time so I turned it on and I had sound. I couldn't pick up a radio station but when I put a cassette tape in it played. I also noticed when I pushed the ac button the compressor would cycle but I didn't have any air. So I changed the resistor and then I had all the fan speeds. I have no idea how or if the O2 sensor was related to my issue but changing that was the only difference. We will see how long it lasts.
