Last year my A/C was fixed. Then winter came. Then I had to buy a new car battery and so I went to a mechanic who I paid to replace the battery with a new one.
My question is: When you replace a car battery, would anything in the A/C system be touched?
I ask because the A/C was working very good before winter and before the car battery replacement and now the A/C does not work at all (air temperature feels the same as the outside air temperature). The car battery is the only work under the hood that has happened in between the A/C working and now the A/C is not working.
The mechanic was one of those large mega-corp chains of auto-replace/auto-care. They did the repair late in the day after 4pm.
