I'm looking into buying a truck that i saw online on auto trader, but noticed it doesn't have A/C listed as a feature. I was wondering if anyone could possibly give me an estimate for how much this would cost. I'm alright with mechanics and if i have a manual and a little help i can install pretty much anything, but an estimate from a professional would be nice. I would be getting the work done in Michigan, just outside of Detroit, so i don't know if that could effect the price.
