so i have an 05 ford mustang had the evap replaced last year and then it blew hot air again after a couple months went back and the said it was a valve so they did it free of charge then a month later again blowing hot and noticed the compressor cycling about every 5 secs, so i took it to a different shop they said it was a little low evacuated and recharged it, said they couldnt find a leak and the compressor was on all the time, but down the road i heard it recylce every 15-20 secs and it was 20min down then road, so is this normal? Ford and the shop say no its not, but alot of people on various forums say its normal.

So maybe you guys have a better opinion on it?
maybe a switch or something went bad?
Should i just buy the gauges for 50$ and test it out myself and whenever it gets low take it to ford?
