Please help me. My AC on my 2006 Grand Marquis is not working.
I run the self-diagnostic test and I had no codes. All lights on the display light up like with the 888 but no code.
The compress is ok. The pipe at the inlet of the evaporator is cool and the pipe at the exit of the evaporator is warm.
I bought the Freon kit and I found out that the pressure on the low side looks ok. The pressure gauge stays in the green area of the gauge (barely touch the blue and the yellow when the pressure gauge moves).
The 3 vacuum valves are working ok.
When I put AC on 15oC it blows warm air. At around 25oC it stops. At 32oC it is hot air.
Few days ago at 15oC it was hot air. It looks like my trouble shooting tests helped a bit
Please help me. Do you think it can be my blend door?
