The day after my last post, I tried the cruise while riding down the highway and it worked. Surprisingly, it worked correctly the entire ride and kept me at a constant speed easily. However, the next day, it didn't work. So I don't know if I want to try and bypass the cruise control or just leave it be and use it when it will work.
My highest priority right now is getting the A/C working correctly. It has apparently been converted to R134a judging by the fittings on the hoses, however, there are no stickers denoting this conversion. The problem with it right now is that it will not stay charged. I have successfully charged the system with one or two cans of refrigerant, but it won't hold a charge for more than a few days. Not very eco-friendly, but more importantly not very wallet friendly. Especially at $6 per can of R-134a.
I am debating whether I should I try and repair the system myself, or just take to someone and let them do the work. Honestly, I trust my work the most, but I don't know if I have all the tools necessary to do the work. First, I think I will price out the parts and see what it would cost me to do it, then shop around for the work.
