Re: How are everyone couping with the virus scare?

Re: Ford fiesta india 2014 a.c confusion

well if you use F instead of C you may get more answers. At idle you're getting about 39degrees and at running 49 degrees right? Usually it is the other way around due to more airflow across the condenser. You may have a marginal control valve if the compressor uses one. If you have to recharge the ...
