Finding somebody who would build me a new airconditioning pipe = happy
Dismantling dash to get old pipe out with sore back = sad
Finding someone to relay my headlights = happy
Having to delay relaying of headlights because fittings on new air con pipe wouldn't fit = sad
Getting new pipe, fitting it, reassembling dash & checking and cleaning all electrical connections = happy nothwithstanding back
Having everything electrical work better than before = happy
Driving home tonight after air cond re-gas with cool air = happy
Sudden flicker of headlights accompanied by burning plastic smell later on said drive = sad.
I think I'll leave Mr auto electrician guru to it and hope he can restore some enduring happiness!
