    I have a 1989 Chevy pickup truck and Im preatty sure that the wiring harness are the same maybe a little different considering you probably have electronic devices... but my a/c heating system inside the truck completely went out I ended up finding the problem on a connecter behind the glovebox should be 4 screws to get that black plastic cover off and just check your connectors...

Check blower motor resistor its a little chip thats usually next to the blower motor. the same thing happened to me i bought a $160 motor replaced it and nothing, so i tried the $20 resistor and that did it i wish i would have tried the resistor first but you live you learn.

Could be your blend door getting stuck thats making that ticking noise. Check your heater hoses to make sure they are getting hot. Check with caution theu may be very hot.

Ticking noise appears to be coming from passenger side under dash, slight but annoying rattle


It might be a restricted or dirty blower motor. Is your heater or ac running? If so, turn it off to see if the noise goes away.

There is a ticking noise everytime my car is on that sounds like the turn signal noise but theres no pattern or order to the ticking. i thought the hazard switch was bad, what could the ticking noise be?


It could be a relay clicking under the dash due to a bad ground circuit somewhere in the vehicle. It would be best to have a professional put an ear to it.

Ticking noise from heat duct


this is a classic sign of a blend door motor or the blend door itself having a problem. the changing of the amount of heat or cold air you get out of your vents use to be obtained by turning the knob on the dash which in turn moved the heat door via a cable now all these cars and trucks have gone to using a electric motor which moves the heat door(the blend door due to the fact it blends hot and cold air to obtain the temperature requested by the driver) when these go bad its often caused by the door itself (being its made out of a plastic ) getting deformed and then binding up inside the heater box(this is the housing in which the heater core and the blend door is housed) when it binds up the blend door motor which is a very small motor with plastic gears ,cannot get the door to the position requested by the driver and continues to try and starts skipping the gears in the motor causing the ticking noise your hearing. the parts are not as expensive as the labor ,to repair requires complete removal of the dash on most vehicles to access the blend door.to test you can usually turn the temp knob back to a point were the motor is not binding and most often the noise will stop until you again attempt to move the knob to get more heat or cool air which again it cannot move the door to the place requested so the ticking noise re occurs

Engine Knocking/Ticking


This may not be your problem, but recently we had chevy in with a ticking on acceleration that turned out to be a leak on the right hand exhaust manifold only slight but enough to make a noise when driven hard. we noticed a carbon mark around the second cylinder in. If it is a petrol engine have you checked the spark plugs are correctly torqued?

''TICKING'' SOUNDS WHEN ACCELERATING AND STOPING


the exhaust was always good for making noises under hard driving as it expands with heat than contracts under cooling but like carlo says more info required
