I have a 1999 Infiniti i30 and I noticed that my a/c was not blowing very cold so I went to the store to buy the a/c pro 20oz charge and sealant. When I attached the gauge and put the can to use I noticed it did not get cold like it was suppose to when u use a freon can. My a/c ended up getting hotter. I bought another can to try the procedure again and my hood slammed against the can and broke the hose. When I was checking the psi it read over 100. Granted the outside temp has been over 100 as well. Don't know if this is normal.. Help please!!!
