I had a coupon from HEB for an oil change, and decided to use it. They changed my oil, rotated my tires, wanted to replace (rather than blow out to clean) both air filters, and replace two tires. Hours later my A/C started blowing hot air and my check tire light came on. I returned and two techs checked my tire pressure and said they were all fine, but couldn't reset the light. Had no idea about the A/C but ""generously"" offered to look at it. I had to leave and didn't feel comfortable with them. Took my vehicle to the mechanic that replaced my A/C system less than a year ago and he informed me that: the tamper evidence cap was broken, the cap to that A/C line was missing, all of my freon was gone, the two switches to the compressor were off (manual unlocking required), one tire had 10 psi too much and two of my valve stem caps were gone. $650.00 later my A/C once again worked, tires at proper psi, but my check tire light is still on; requiring me to take it to yet another shop for troubleshooting. Spoke with the owner who immediately told me that the A/C was incompetent and ""screwed"" me, his tech doesn't know anything about A/C systems so couldn't have done anything to it and that he heard nothing while my vehicle was in the shop; therefore, there's no way his shop could be responsible for what happened despite the problems starting within hours of having the oil changed. Right....
