Just got my A/C fixed - at a great saving. On my way home, I realized that my economic gauge will not stay at the far left now when the car is at stop.

If I put it to P or turn A/C off, the needle will get back but not while it was in D w/ A/C on. Is this normal? Sounds like the engine is putting in extra work to get the A/C going.

Sounds normal to me, the compressor puts an added strain on the engine. You gotta remember a normal AC compressor is making more than 1k psi. At least the last time I worked on an AC.

Click ‘submit’ once and wait about thirty seconds for the server to respond – I know it looks like the ‘submit’ did not take but the server is really slow.

What the econogauge is doing is normal.

Unfortunately my AC doesn't work. The previous owner converted it to R134a but whenever I hit the AC button the compressor doesn't turn on. So, I bought a refill cannister and connected that to the system, filled it up to optimum pressure, and with the can still connected I could hear the compressor kick in.

Unfortunately, after disconnecting the cannister, the compressor doesn't kick in, and when I check the pressure it reads within optimum range.

What's wrong with my A/C, and where did you get yours fixed for a good price, also what was the problem with yours?
