Complete Guide to Porsche 944 Outside Mirror Parts

Owning a Porsche 944 means maintaining a classic that still turns heads. The outside mirrors are a small but critical piece—they complete the car's sleek lines and provide essential visibility. Over time, mirror parts can fail: glass cracks, motors burn out, housings fade, or gaskets leak. Replacing them correctly keeps your 944 looking sharp and driving safe. This guide covers everything you need to know about Porsche 944 outside mirror parts, from identifying the right style to choosing between OEM and aftermarket, plus practical installation advice.

Understanding Porsche 944 Mirror Styles

The Porsche 944 came with two distinct mirror designs during its production run (1982–1991). Knowing which you have is the first step in buying the correct parts.

Early Mirrors (1982–1985.5)

Early 944s feature a smaller, slightly more rounded mirror housing. The glass is flat (non-convex) and the mirror adjusts manually via a lever inside the car. These mirrors are often referred to as "manual" or "non-electric." The base gasket is separate and prone to cracking.

Late Mirrors (1985.5–1991)

With the 1985.5 model update, Porsche introduced larger, aerodynamically shaped mirrors. These are power-adjustable (electric) and feature a convex driver-side lens for a wider view. They mount on a triangular base with a rubber gasket that often shrinks or rots. The internal motor assembly is a common failure point.

Important: 1985.5 models can have early or late mirrors depending on build date. Verify by checking if the mirror has an electrical connector (late) or mechanical cable (early).

Common Porsche 944 Mirror Problems

Before buying parts, diagnose what's wrong. Here are the typical issues and the parts you'll need.

Cracked or Hazy Mirror Glass

The glass itself can shatter from a rock hit or become cloudy from age. Replacing just the glass is often the cheapest fix. Early mirrors use a plain flat glass; late mirrors use a convex driver glass and a flat passenger glass. Some aftermarket options include blue-tinted or anti-glare coatings.

Non-Functioning Electric Motor

If your late mirror won't adjust electronically, the motor inside is often dead. You can buy a complete replacement motor assembly or just the gear set if the gears are stripped. Many motors fail because of dried-out grease; sometimes cleaning and re-lubricating the old motor works, but a new motor is more reliable.

Broken or Faded Mirror Housing

The plastic housing can crack from age or impact, and the paint may peel. Housings are available in primed (ready to paint) or finished in factory colors. Matching the color is important because the mirror housing contrasts with the body—especially on Guards Red or Black cars. If you can't find an exact color match, a primed housing painted by a body shop is the best route.

Leaking or Dried-Out Gasket

The rubber gasket between the mirror base and the door skin seals out water. Once it shrinks or cracks, water can drip into the door, leading to rust and electrical issues. Replacing the gasket is a simple fix that prevents bigger problems. Always buy a new gasket when reinstalling a mirror.

OEM vs. Aftermarket Porsche 944 Mirror Parts

When shopping for mirror parts, you have two main choices: original equipment manufacturer (OEM) parts from Porsche (often made by Star or Fiamm) or aftermarket replacements from brands like URO, Dorman, or Pelican Parts. Here's how they compare.

OEM Parts

• Pros: Exact fit, high-quality materials, paint match (if pre-painted), lasts many years.
• Cons: Expensive, especially for complete assemblies. Some OEM glass is no longer available.
• When to choose: You want a concours-level restoration or need a specific color match without repainting.

Aftermarket Parts

• Pros: Lower cost, widely available, often includes upgraded features (e.g., blue glass).
• Cons: Fit can vary—some mirrors wiggle at high speed, paint quality differs, plastics may be less UV-resistant.
• When to choose: Daily driver or track car, you're on a budget, or OEM is discontinued.

Recommendation: For glass and gaskets, aftermarket is fine and much cheaper. For housings and motors, OEM offers better durability, but aftermarket can work if you check reviews carefully. Avoid the very cheapest no-name parts.

Step-by-Step Installation Overview

Replacing a mirror assembly or just the glass is a DIY job that takes about an hour. Always disconnect the battery before working with electric mirrors.

Replacing Mirror Glass Only (Late Models)

1. Gently pry the old glass out from the bottom using a plastic trim tool. The glass is held by clips—do not force it.
2. Disconnect the heating element wires (if equipped) by carefully unclipping them.
3. Remove any remaining adhesive from the backing plate.
4. Press the new glass onto the motor mount, ensuring the heated pads align.
5. Reconnect wires and test adjustment before finalizing.

Replacing the Entire Mirror Assembly

1. Remove the interior door panel to access the mirror mounting bolts. On late models, you'll also disconnect the electrical connector.
2. Unscrew the three (early) or two (late) bolts holding the mirror to the door.
3. Lift the mirror off the door. Remove old gasket and clean surface.
4. Apply new gasket, position new mirror, and tighten bolts to 8–10 Nm (not too tight—plastic housings can crack).
5. Reconnect wiring and test function. Reinstall door panel.

Parts Compatibility Across 944 Years

Not all mirror parts fit every year. Here are key compatibility notes:

• Manual vs. Electric: Entirely different mechanisms. Manual mirrors lack the motor and wiring. Retrofit is possible but requires door harness changes.
• Driver vs. Passenger: Late driver mirrors are convex; passenger is flat. Aftermarket sets often sell as a pair.
• Gasket Shape: Early gaskets are rectangular; late gaskets are triangular. They are not interchangeable.
• Housing and Base: The attachment holes on doors changed slightly in 1985.5, but some aftermarket housings come with adapters.
• Heated Mirrors: Some 944s have heating elements. Not all aftermarket glass includes heater pads—check before buying.

Practical Recommendations for Buying Mirror Parts

Here are specific, actionable tips for finding the right parts for your Porsche 944 outside mirror:

• For glass: Buy from a specialty 944 parts supplier (e.g., Only944, Pelican Parts). Look for “OE quality” lenses with correct curvature. Avoid universal stick-on mirrors.
• For gaskets: Always get new rubber gaskets. They are inexpensive (around $10-20) and prevent costly water damage.
• For motors: If your motor is dead, consider buying a used OEM motor from a parts dismantler—they often outlast new aftermarket ones. Alternatively, aftermarket motor assemblies from URO are an okay budget choice.
• For housings: Order primed and have a body shop spray factory paint for best results. Pre-painted housings can be slightly off-shade.
• Complete assemblies: If you want a hassle-free swap, a complete aftermarket assembly (housing, glass, motor, gasket) saves time. Expect to pay $100–$250 per side. OEM complete mirrors run $400–$800 (if you can find them).

Final Recommendation

Start by pinpointing exactly what's broken. For most owners, replacing the glass and gasket gives the biggest improvement for the least money. If the electric motor fails, opt for a known-good used OEM unit before trying a cheap aftermarket motor. On a budget car, an entire aftermarket mirror assembly works fine—just ensure the paint matches. For a show car, source OEM parts from a specialist or salvage yard. Whichever path you choose, always replace the gasket to keep moisture out. With the right Porsche 944 outside mirror parts, your 944 will look complete and stay roadworthy for miles to come.
