Hello. Last DMV renewal I missed it somehow and by the time I was trying very high penalty and late fee. So I PNO'd it. My son recently got his DL and has basically taken the 2nd vehicle so I should renew it soon.
That said there is a neat inspection chart that I found in my repair info:
Engine @ 1500 rpm
Blower HI
A/C ON
Temp @ MAX COLD
All doors fully open (I assume this means trunk also)
1. Bubbles visible Insufficient 1) check for leak and repair if found 2) add freon until bubbles disappear
2. No bubbles Empty, Insufficient, or Excessive See 3 and 4
3. No temp difference between compressor inlet and outlet Empty or nearly 1) check for leak with halogen leak detector and repair if found 2) add freon until bubbles disappear
4. Considerable temp difference compressor inlet and outlet Correct amount or excessive See 5 and 6
5. Immediately after A/C OFF, refrigerant clear Excessive 1) Drain or discharge 2) Pull vacuum and charge pure freon
6. Immediately after A/C OFF, refrigerant foams and then clear Correct
*IF ambient higher than usual but cooling sufficient, bubbles permissible
Hope this helps...
