Please help: Time to tackle my A/C issue now!!!
My cay has stopped cooling twice now. The first time was 1 year ago, I had it recharged and it lasted about 5 months and then started blowing cold. The guy that did it did a pressure test and it passed so he told me that it would be good now.
The second time (month ago) it started blowing hot and I took it in to an Indy shop here in Killeen and I told him that I had to have a leak since this was the second issue in 5 months. They did a UV dye test and a pressure test and both passed, no leaks detected with UV. Now they want to recharge with freon and UV yet again! I am afraid that nothing will be found yet again so I did the A/C diagnostic and these are the values I got.
can someone tell me if they see anything that may need to be replaced! The temperature outside was 60 degrees. Oh yeah my EC light has been on for a month as well.
1 in-car temp (91)
2 temp outside (100)
3 heater core temp, left (159)
4 heater core temp, right (87)
5 evaporator core temp (75)
6 engine coolant temp (192)
7 refrigerant pressure (in bars) (1)
8 refrigerant temp (99)
9 not used (0)
10 blower control voltage in range .8 - 6V (max) (5.0)
11 air pollution sensor (N/A no reading for this!!)
12 sun sensor (N/A)
20 control current of aux fan (0)
21 engine RPM (x 100) (6)
22 vehicle speed, km/h (0) I was parked
23 terminal 58d battery charge, percent (100)
24 battery voltage (14.1)
40 software status register (6)
41 hardware status register (3)
I also had the following come up:
42 (200)
43 (8)
Thanks for any help!!
