pic, What relay is this next to the Klima relay that controls the compressor. My compressor wouldn't switched to 134r freon,new dryer and evaporater and compressor. Jumped compressor from +on battery and it worked. Jumped the low pressure lines together and no engagement. I pulled a 10a fuse from this relay, and put a 15a cause that was all i had, and the compressor came on and worked for a day. What function does this relay have . also in what relation to the compressor or Klima. Today I changed it to a 7.5 fuse just in case the 15 is why it stoped again,maybe shorting the Klima. Any thoughts on the circled relay in the attachement. 1985 300sd 126
