98 SE - A/C recharge only lasts about a month
Well, you guys saved me $ the last time I had trouble so here goes. I had the A/C recharged about a month ago and it worked great until now. At the time I had it recharged they put dye in the system to see if they could see the leak. Well, it didn't show up that day so they sent me on my way. I was hoping it would last the whole summer. Now the car is 600 miles away from that shop and blowing warm again. I'd like to check for the obvious before starting over with a new shop.
First, what is the best way to look for the dye? Do I need a light? Is it easier to see from the top or from under the car?
Second, I know sometimes these things fail across the board, is there a common fault that I should look at or replace first? Any pointers would be great. Thanks
