Unlike many other vehicles, the blower motor in a 1997 GMC Jimmy is sealed inside the blower motor compartment from the factory. A perforated access panel must be cut and removed in order to replace a faulty motor. The most common sign of a faulty blower is squealing or screeching when the blower fan is set to a medium or high speed setting. This is due to the motor bearings failing after many hours of use. Another common problem with the blower motor is failure of the motor armature assembly. In this situation, the only symptom would be a non-responsive motor despite the desired speed setting.

Instructions

Removal

1

Pop open the hood and support it with the hood prop. Disconnect the negative battery terminal with an 8 mm battery wrench.

2

Remove the bolts holding the VCM to its mounting bracket with a ratchet and metric socket. Leave the VCM connectors attached and swing it to the side and out of the way.

3

Squeeze the spring clamp holding the feed hose to the coolant reservoir with a pair of pliers and slide it away from the end of the hose. Remove the coolant feed hose from the reservoir. Remove the bolts holding the reservoir to the vehicle with a metric socket and ratchet. Remove the reservoir from the vehicle while turning it to its side to prevent coolant from spilling out. Pour the coolant into a drain pan and set the reservoir aside.

4

Disconnect any electrical connectors blocking the blower motor compartment. Remove the screws at the bottom of the from blower motor cover with a ratchet and metric socket. Disconnect the blower motors electrical harness.

5

Cut along the perforated cut lines with a utility knife to separate the upper portion of the cover from the blower motor compartment. Grip the upper half of the cover and tear the remaining section of the access cover away from the blower motor compartment along the tear lines. Cut along the perforated lines on the bottom portion of the cover with a utility knife and then tear the remaining section away from the blower motor compartment until the lower access panel is free.

6

Remove the screws holding the blower motor in place and remove the blower motor from the blower motor compartment.

Installation

7

Set the new blower motor into position inside the access panel and reinstall the blower motor retaining screws with a ratchet and metric socket.

8

Join the tabs of the upper and lower blower motor access panels together to form one panel. Cut a piece of black duct tape to the width of the lower access panel and affix it to the bottom leading edge of the lower access panel.

9

Set the access panel into place and reinstall the panel retaining screws. Align the cut areas of the access panel with the blower motor compartment and seal the cut line areas with black, self-adhesive weather stripping. Let the adhesive set for 15 minutes before proceeding.

10

Reconnect the blower motor electrical harness and the electrical connectors in front of the blower motor compartment.

11

Set the coolant reservoir into position and reinstall its retaining bolt. Reconnect the coolant feed hose and reposition the hose clamp.

12

Set the VCM into position and reinstall its retaining bolts. Reconnect the negative battery terminal and full re-fill the coolant reservoir with a 50/50 mixture of distilled water and DEXCOOL coolant until the level reaches the FULL COLD mark.

13

Turn the ignition on and test the blower motor on each fan setting.

A vehicles engine and transmission is stabilized by the motor mount. A motor mount also keeps you from feeling the full vibration that an engine is capable of causing. Because of this, information on different motor mounts for cars can be beneficial.

Regular

A regular motor mount is simple in the way its designed. It has a metal plate, as well as an insulation block made from rubber. The rubber absorbs vibration, while the metal bracket of the mount is for engine support.

Hydro

Hydraulic motor mounts can be found on many vehicles, and have chambers with hydraulic fluid in them. These motor mounts are known for controlling engine noise and vibration and can often be found in luxury vehicles.

Internal Valving

Some hydraulic motor mounts are equipped with internal valving. Because of the way they function to control vibration changes according to the engines rpm, they are often erred to as switchable hydraulic mounts.

You rely on the windshield wipers of your 1990 Chevrolet van to keep your field of vision clear when you are on the road in poor weather conditions. If the wipers fail and you confirm that the relay is intact, the wiper motor might be to blame. Buy a replacement wiper motor from an auto parts retailer, and change it at home.

Instructions

1

Park the van, and engage the parking brake. Raise the hood, then rest it on the support rod.

2

Use a Phillips screwdriver to remove the screws from the cowl mounted just under the wiper arms, inside the engine compartment. Lift the wiper arms up away from the windshield glass. Push the retaining clip at the base of the wiper arm, and lift it off the mounting post.

3

Remove the cowl from the engine compartment. The wiper motor is just below the cowl mounting area, beside the heater duct.

Excessive shaking during acceleration or when driving up hills can point to a broken front motor mount on the Honda Odyssey. The motor mount is located in the center of the engine compartment, between the lower part of the motor and radiator. Examine the mount from under the engine compartment. If the rubber is cracked, replace the motor mount before the vibrations cause any other parts on the Odyssey to fail.

Instructions

1

Drive both front wheels of the Odyssey onto ramps. Secure wheel chocks behind both rear wheels. (Alternatively, raise both front wheels with a jack and secure them on jack stands.) Open the hood of the Odyssey.

2

Place a jack under the oil pan, with a scrap of wood between the jack and the oil pan. Raise the jack slightly until the wood touches the pan.

3

Remove the four bolts below the front motor mount with a socket wrench. Remove the one nut above the front motor mount.

4

Raise the jack under the oil pan until the top motor mount bolt is free from the motor. Secure a jack stand or additional wood under the motor as a safety precaution.

5

Remove the motor mount by lifting and sliding sideways, up and out. Replace with a new front motor mount.

6

Replace the four bolts under the front motor mount and secure to finger tightness. Remove the jack stand from under the motor. Lower the jack slowly, allowing the upper motor mount bolt to slide into the front mount bracket. Remove the jack and wood.

7

Replace the upper motor mount bolt and tighten to 40 ft-lbs. (54 N-m). Tighten the four lower bolts to 28 ft-lbs. (38 N-m).
