I was having problems with my ac compressor staying on, it was always on. I began looking for the klima relay, I looked where everyone told me to look, behind the battery by the firewll. All I could find is a small silver relay that someone pigtailed in where I assume the klima goes. I changed the relay that was pigtailed and the compressor shut off. It worked for a couple of days and now the compressor is back on, even with the climate control shut down. the big question is, should my car have a klima. Whomever pigtailed the relay did a very good job, very neat, I assume whomever did it knew what they were doing. Thanks Ed
