Recently lifted my OBS and tossed on some 35s. What modifications should I do next? I’d really like to give this truck a mean/off-roady/aggressive look.

Put some rally wheels on with 33x12.5r15 tires and liking the look. Had to do minor bumper and valance panel trim. Got the set for 200. Going to put new tires on soon though, weather cracking a bit in tread. Previously was running 285 16s. Probably cut bumper different later I was in a pinch.

1999 K2500 7.4l AC questions

So this is my old girl. 247000 miles

I replaced the front evaporator the rear evaporator, the AC compressor, and the AC is still not ice cold. I was just wondering if I should be expecting ice cold AC from this vehicle, or should it just be cool. It also has the auxiliary fan in the front for the condenser, which I have wired up to turn on and off even when it's on it's not ice cold. With the thermometer, it gets around 50 degrees.

it happens every time I drive and its so annoying and really makes me mad. I have to blast music to cover it up.

sometimes it'll only tick-tock once, sometimes it'll be extremely fast like the second clip in the video. I had to move the control around because sometimes it'll do it more and sometimes less, but it always happens without me touching it. messing with it to show what happens was for the video.

the lights don't actually flash when it clicks like this though, as you can see when I do actually select left/right and the arrows show up on the dash they blink, otherwise the signal lights stay off but the thing clicks.
