Visual Inspection

Visually inspect all electrical wiring. Look for chafed, stretched, cut or pinched wiring. Ensure electrical connectors fit tightly and are not corroded. Ensure vacuum hoses are properly routed and not pinched or cut. If necessary, see appropriate VACUUM DIAGRAMS in VACUUM DIAGRAMS - ASTRO & SAFARI article or VACUUM DIAGRAMS in VACUUM DIAGRAMS - BLAZER, JIMMY CANADIAN, SONOMA & S10 PICKUP article to verify routing and connections. Inspect air induction system for possible vacuum leaks.
