I was having a similar problem with my 1998 turn signal, except it was turn signal left - sometimes. I sprayed CRC 3-36 (like WD-40) into the hazard light switch on top of steering column and worked the hazard switch in and out several times. The problem has disappeared and my hazard flashers started working again. The hazard lights had not functioned since I bought the car from the state patrol in 2003! This saved me time, money, and I had nothing to lose trying it. Disconnect the neg. battery terminal first just to be safe.
