I have a problem with the rear ac sometimes I can get it to come on but if I step on the gas to hard it turns off and start blowing hot air at the floor and than it takes a while to get it going again I have to turn it on and off several times to get to start blowing again. I been dealing with this problem for the last 2 years and need to get it fix some how. Anyone has had this problem before any help will be appreciated. Thank you.
