Hello all, I just purchased a used 91 Nissan Pickup for my college vehicle. Before I take it off to college, I have a few things I need to fix on it and was wondering if OT had any suggestions. First, my air conditioner just doesn't seem to work right. The light will come on, and at night, the airs cold, but during the day, just hot air blows. Any clue as to what could be wrong? Next, the fuse box on the drivers side has recently had all its fuses replaced. Unfortuately, all the fuses are of a higher voltage than what's on the diagram. Is there any particular reason for this, and should I change them to the recommended diagrams? Finally, I have to replace the tailights and headlights on my truck. I looked on ebay and saw some nice looking Euro tail lights and headlights. How hard would it be to install them, and would I have to do any major modification? Thanks for your help!
