power steering ?

I Have a 1989 Chevy barretta, 4cyl. automatic with a/c. I live in New York and in the winter time when the temperature is colder outside like below 32 degrees, when I start the vehicle after it has sat overnight , when i start it up and i turn the wheels the lights dim and the voltmeter on the dash goes way down. It does this maybe through 3 or 4 turns then it ceases. it seems to do it worse the colder it gets. it was bad the other day when the temp got down to 10 degrees. I started the car and backed out of the drive and when I turned I thought it was going to stall. By the time I hit the third turn everything was fine. Any suggestions.

Now with the colder weather oil "gets thicker". It is harder for the pump to push that fluid through because it is thick. There is usualy a switch on the p/s pump to tell the car to raise the idle so that with the extra load on the engine (due to the pump "pushing " fluid to turn) wont stall. If the switch isn't working the car may stall/ lights dim due to alternator turning slower. This may not be noticeable in the summer because the oil is "thinner". Take it to a technican so it can be diagnosed for sure.
