124 air conditioner does not cool
my 87 300E was converted to 134a in 7/01 for $1700 (reman compressor, expan valve,receiver,ac clutch) and has cooled well until now. About one day after fixing my fuel level sender and putting my speedo back in the dash, the ac no longer cools adequately. Where do I start to dx? I think my temp sensing functions are ok. Is there a link that I can find to start working? I might buy guages if we think there is a 134a leak. Is there a pure ac shop in Fort Worth, perhaps Dallas?
