Guys I have come across a little problem. During city driving with AC on. My Pajero SWB 1989 4D56TD's steering became hard... the weather was quite hot temperature soaring to 40 degrees. I felt that my steering was getting hard at one point I was literally going to hit a Rikshaw :S....
During morning time or when engine is not that hot steering is working fine, it happens only when the heat guage is near center and AC is on.
Any idea what seems to be the problem?
