I recently bought a compressor from Mercedes shop and had my mechanic install it. After he installed it, it didn't work - he said that the compressor was cycling between "On and Off" and his readings for the coolant indicated high pressure. What could cause this? He said he would eventually find out why this was happening if he was allowed to work on it for another day. Any help or suggestions will be appreciated.

thanks,
